2. The dimensions of a rectangle can be given by x + 7 and x + 2. If the area of the rectangle is 66 square inches, what are the dimensions of the rectangle?
Answer:
(x+7)(x+2) = 66
x^2+9x+14=66
x^2 + 9x -52 = 0
(x+13)(x-4) = 0
x = 4 bc the other root, -13, can't be used (it would make the dimensions negative values)
Please find the missing angle of this Shape.
3/4x-1 1/2x+7
23
32
46
92
Answer:
92 is your answer
Step-by-step explanation:
we have
3x/4-1=x/2+7 side of square are equal
3x/4-x/2=7+1
(3x-2x)/4=8
x=8×4=32
length =3×32/4 -1=24-1=23
now
perimeter=4×length=4×23=92 units
Answer: The perimeter of the square is 92 units.
Step-by-step explanation:
All four sides of a square are equal. Set the given values 3/4x - 1 and 1/2x + 7 equal to one another. It should like this: 3/4x - 1 = 1/2x+7. The next step is solving for x. We get x = 32 as our answer. See the image of the work below if you are confused. :) Next, plug in this answer to the original equations: 3/4x-1 and 1/2x+7.
3/4(32) - 1 = 23
1/2(32) + 7 = 23
After basic substitution, we will conclude that each side of the square is 23 units long. To find perimeter use the equation 4s (let s represent sides). 4(23) = 92 units. Hope this was helpful!
how can you determine if two triangle angles are similar using their angle measurements???? In ur own words !!
Please help
Answer:
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

1) Matthew can run of a mile in of an hour. What is the unit rate?
2x-y=8
x+2y=4
for the system of equation above, what is the value of x+y?
Answer:
4
Step-by-step explanation:
2x-y=8 ---> y= 8-2x
substitute y=8-2x into x+2y=4
x + 2(8 - 2x) = 4
x + 16 - 4x = 4
-3x = -12
x = -12/-3
x = 4
substitute x=y into y=8-2x
y = 8 - 2(4)
y = 8 - 8
y = 0
therefore,
x+y= 4+0
4
btw i like ur jimin pfp besty :)
can someone j help me w this, ive reposted it twice now :-(((( due in an hour please help!:( will give brainliest
Step-by-step explanation:
I got you,
a) Work...
First equation: y = 4x + 3
Second equation: y = 2x + 11
If he wants to play 2 games...
y = 4 (2) + 3
y = 11
y = 2 (2) + 11
y = 15
Answer for part a: If a customer wants to rent shoes and play two games, they'll pay more with the new price plan. With the current price plan, they'll pay 11 dollars, but with the new price plan, they'll pay 15 dollars.
b) Work...
seven games...
y = 4 (7) + 3
y = 31
y = 2 (7) + 11
y = 25
Answer for part b: If the customer wants to play 7 games, including the shoes, they would pay less using the new plan. If the shes were not included, the new price will still be less. With the shoes, 7 games, with the original plan, is 31 dollars but 25 dollars with the new plan. If they didn't want to rent shoes, they would pay 28 dollars with the original plan but only 14 dollars with the new plan. All in all, they spend less on the new plan anyways.
I hope this helps :)
What is m∠1?
DUE TODAY!!
Answer:32
Step-by-step explanation:add them to 180
What is m∠1? Help me, please
Answer:
∠1 = 72°
Step-by-step explanation:
exterior ∠ = the sum of two opposite(remote) interior ∠s
∠1 = 37° + 35°
=> ∠1 = 72°
Answer:
72 degrees.
Step-by-step explanation:
Angle 1 is one of the triangle's exterior angles. The exterior angle theorem states that the measure of a triangle's exterior angle is equal to the sum of the opposite interior angles. Therefore, m<1 is equal to the sum of 35 and 37:
35+37=72
m<1 = 72 degrees

The population of a certain animal species decreases at a rate of 3% per year. You have counted 80 of the animals in the habitat you are studying. Write a function that models the change in the animal population.
A: f(x) = 80(3)^x
B: f(x) = 80(.03)^x
C: f(x) = 80(.97)^x
D: f(x) = 80(1.03)^x
Answer:
C. f(x) = 80(.97)^x
Step-by-step explanation:
If the population decreases by 3% each year, then it would be the same as multiplying it by 97% or 0.97 each year.

Answer:
Fred's age: 26 Natalie's age: 15
Step-by-step explanation:
F + N = 41
-) F + 3N = 71
____________
=> -2N = -30
=> N = 15
F + 15 = 41 => F = 26

Mike took an uber from his home to the airport. The driver charges an initial fee of $6 and $3 per mile. The total fare was $24 not including the tip. How many miles did Mike travel by uber on this ride? *
Answer:
About 5 miles
Step-by-step explanation:
At first, I thought it would be 6 miles because 6x3 is 18 plus the initial 6 dollars which is 24. However, it says that it does not include the tip, which means that Mike DID tip the driver. So there has to be some space for the tip. If it was 6 miles it would be 24 dollars, but there is no more space for the tip. So it has to be 5 miles, because that will be 21 dollars, and assuming the tip could be about 3 dollars, then that would total up to 24 dollars.

A motorist takes 80 minutes to travel 120km. find his speed
Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.

Harvey has $390 in a savings account that earns 6% simple interest each year. How much interest will Harvey earn in 2 years, assuming she does not add or take out any money? How much total money is in the account at the end of two years?
Answer:
She will earn $46.8 of interest. $436.8 is in her account total after the two years
Step-by-step explanation:
You would find out how much 6% of $390 is which would be $23.4 and then you would find out how much it would be after two years so you would $23.4 times two which is $46.8 so the interest would be $46.8. Then you would add the interest to the $390 that was put into the savings so you would do $390 + $46.8 = $436.8
