2x^2 + 163 - 8 = 0
Answer:
D
Step-by-step explanation:
[tex]2x^2+16x-8=0[/tex]
Simplify:
[tex]x^2+8x=4[/tex]
Rewrite in the form [tex](x+a)^2=b[/tex]:
[tex]x^2+8x=4[/tex]
Add [tex]4^2[/tex] to both sides:
[tex]x^2+8x+4^2=4+4^2[/tex]
[tex]x^2+8x+4^2=20[/tex]
[tex]\left(x+4\right)^2=20[/tex]
[tex]x+4=\sqrt{20}[/tex] or [tex]x+4=-\sqrt{20}[/tex]
x = -4±[tex]\sqrt{20}[/tex]
x= -4±[tex]2\sqrt{5}[/tex]

Step-by-step explanation:
Todd can run 1/2 a mile in 1/12 of an hour. what is todd’s rate in miles per hour?
Answer:
Step-by-step explanation:
(1/2 mile)/(1/12 hour) = 12/2 = 1 mph
How long it takes someone to walk a trail depends on the length of the trail, which you did not provide. The formula is distance = rate*time, so time = distance/rate. You know the rate = 1 mph
The area of a square is 16x^2 -40x+ 25. What is the perimeter of the square?
Answer:
Perimeter = 16x-20 units
Step-by-step explanation:
Given: 16x^2 - 40x + 25
Reduce perfect square trinomial: (4x-5)(4x-5)
4x-5 is your side length. Since the perimeter of a square is 4s, then the perimeter is 4(4x-5)=16x-20
find the value of x then find the angle measures of the polygon 65, x, (x-5)
Answer:
x = 60
Step-by-step explanation:
Assuming that there are no secret angles unmentioned, the figure in question is a triangle, as it has 3 angles. With this knowledge, we also know that a triangle contains 180°. So, we can do the following to solve for x.
65 + x + (x - 5) = 180
2x + 60 = 180
2x = 120
x = 60

Answer: A- 12.5 million
Step-by-step explanation: all you have to do is 125% of 10 million and you get 12.5 million.
Answer:
40 million
Step-by-step explanation:
125% of x
125/100 * x = 1.25x
x+ 10 = 1.25x
(subtract x from both sides)
10 = 1.25x - x
10 = 0.25x
(divide both sides by 0.25)
10/0.25 = x
x= 40

Jayesh determines that he needs to sell more than $200 worth of fruit athis produce stand in order to make a profit. Part A.Which inequality represents the fruit sales,s, in dollars, forwhich Jayesh will make a profit?A s< 150 Bs< 200 Cs> 200 Ds> 250
Answer:
s > 200
Step-by-step explanation:
Note that
> means greater than
< means less than
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
If he needs to sell more than 200, sales has to be greater than 200 = s > 200

(x+2)^2=1
Answer: x = -1, -3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Taking the square root of both sides leads to
x + 2 = ±1
which in turn comes out to x = -2 + 1, or x = -1, and x = -2 - 1, or x = -3
A line segment AB is increased along its length by 25% by producing it to C on the side of B . If A and B have the coordinates ( 1 , 2 ) and ( 5 , 6 ) respectively then find the coordinates of C.
Ans : ( 6 , 7 )
*Please show your workings*
Answer:
C = (6, 7)Step-by-step explanation:
Coordinates of point B in terms of A and C:
x = x₁ + (x₂ - x₁)*a/(a + b)y = y₁ + (y₂ - y₁)*a/(a + b)B(x, y) = (5, 6), A(x₁, y₁) = (1, 2), C(x₂, y₂) = ?Find the coordinates:
5 = 1 + (x₂ - 1)*4/5 ⇒ 4 = 4/5*(x₂ - 1) ⇒ x₂ - 1 = 5 ⇒ x₂ = 66 = 2 + (y₂ - 2)*4/5 ⇒ 4 = 4/5(y₂ - 2) ⇒ y₂ - 2 = 5 ⇒ y₂ = 7C = (6, 7)A square sticky note has sides that are 7 centimeters long. What is the sticky note's area?

Answer:
Step-by-step explanation:
3(x +2 ) = 18 {Use distributive property: a(b +c) =a*b + a*c}
3*x +3*2 = 18
3x + 6 = 18 {Subtract 6 from both sides}
3x = 18- 6
3x = 12 {Divide both sides by 3}
x = 12/3
x = 4

PLEASE HELP FOR #2abc!!
Answer:
a) 2
b) 1
c) y =mx+b
Step-by-step explanation:
Slope = rise/run = Δy/Δx = 2/1 =2 [Δ means difference between 2 values]
To find slope we need to find by how many difference do the x and y increases or decreases. Here y increases by 2 and x increases by 1.
The constant just another way of asking y-intercept.
The slope-intercept form y=mx+b. [m=slope, b= y-intercept]
We will choose point (1,3) to input into the equation. You can use any point it would give the same answer.

Find 3[g(4)] if g(x) = -2x + 10
Answer:
6
Step-by-step explanation:
= 3[-2(4) + 10]
= 3(-8 + 10)
= 3(2)
The function is given as g(x) = -2x + 10 then the solution of the 3[g(4)] would be equal to 6.
What is a function?A function is a type of relation, or rule, that maps one input to a specific single output.
Functions that are formed by composing two or more functions in a way that one's output is another's input are called composite functions.
They are also called functions of functions.
We have to find 3[g(4)] if g(x) = -2x + 10
3[g(4)] = 3[-2(4) + 10]
3[g(4)] = 3(-8 + 10)
3[g(4)] = 3(2)
3[g(4)] = 6
