Answer:

30y+14

Step-by-step explanation:

add the values of all the sides together: (5y+4) + (5y+4) + (10y+3) + (10y+3) = (5y + 5y + 10y + 10y) + (4 + 4 + 3 + 3)= 30y + 14

Answer:

[tex]k=\pm3[/tex]

Step-by-step explanation:

[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant [tex]\Delta = b^2-4ac[/tex] (or, if b is an even number, 1/4 of it) is zero.

I see it! I see it!

Stare at it for a while. First term is [tex]3(2x)^2[/tex], third term is [tex]3(1)^2[/tex], we are missing a double product, but we can play with k. For the LHS to be [tex]3(2x\pm1)^2 = 3(4x^2\pm4x+1) = 12x^2\pm12x+3[/tex] you just need [tex]4k= \pm12 \rightarrow k=\pm3[/tex].

I don't see it...

Then number crunching it is. Set the discriminant to 0, solve for k

[tex]\frac{\Delta}4 = 4k^2-12\cdot 3 =0 \rightarrow 4k^2=36 \\k^2 = 9 \rightarrow k=\pm3[/tex]

Answer:

100 square cm

Step-by-step explanation:

There are 1(1/6) pound of vegetables in each bowl.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of bowls = 6

Number of carrot sticks = 4 pounds

Number of celery sticks = 3 pounds

The number of carrots in each bowl.

= 4/6

= 2/3 pounds

The number of celery sticks in each bowl.

= 3/6

= 1/2 pounds

The number of pounds of vegetables in each bowl.

= 2/3 + 1/2

= (4 + 3)/6

= 7/6

= 1(1/6) pounds

Thus,

There are 1(1/6) pound of vegetables in each bowl.

Answer:

Coordinates or points would be  (0,2), (1,2.6) (2,3.2) (3,3.8)

Step-by-step explanation:

Formula

w(x) = 3/5x +2 in each coordinate I have a x so for example 3.

I would rewrite this as 3/5(3) + 2

w(x) = 3/5x +2

w(3) = 3/5(3) + 2

First we must know this,

The length of the third side of a triangle must be less than than the sum of the lengths of any two sides of a triangle.

So, Now let us check one by one :

Option 1 : 5m, 6m, 8m

So, 5m, 6m, 8m can form a triangle .

Option 2 : 10m, 10, 2m

So, 10m, 10m, 2m can form a triangle .

Option 3 : 19m, 34m, 15m

So, 19m, 34m, 15m cannot form a triangle .

Option 4 : 3m, 16m, 14m

So, 3m, 16m, 14m can form a triangle .

Answer: 549

Step-by-step explanation:

Using the concept of arithmetic sequence, the 5000th term can be obtained using the relation 4 + (5000 - 1)9

For an arithmetic sequence, the nth term is calculated using the relation :

Here,

First term, a = 4

Common difference = 2nd term - 1st term = 13 - 4 = 9

nth term = 5000th term

The expression would be :

The required expression would be : T(5000) = 4 + (5000 - 1)9

Step-by-step explanation:

The slope of the handicap ramp is 1/2

The slope of the handicap ramp is gotten from the equation for the slope of a line, m with endpoints (x₁, y₁) and (x₂, y₂).

m = (y₂ - y₁)/(x₂ - x₁)

Since one point of the ramp can be identified by the ordered pair (d, 4d) and another point on the ramp is identified by the ordered pair (3d, 5d), we have that (x₁, y₁) = (d, 4d) and (x₂, y₂) = (3d, 5d).

Substituting the values of the variables into the equation, we have

m = (y₂ - y₁)/(x₂ - x₁)

m = (5d - 4d)/(3d - d)

m = d/2d

m = 1/2

So, the slope of the handicap ramp is 1/2
