Answer:
I think that the answer is A
So you want to find two numbers that add up to -13 and multiply to
40. You can find the factors of 40 and find the pair that adds up to
-13. -8 and -5 multiply to 40 and add up to -13.
<span><span>(x−5)</span><span>(x−8)</span>=<span>x2</span>−13x+40</span>
You can use foil to test it
<span><span>x2</span>+<span>(−8x)</span>+<span>(−5x)</span>+40=<span>x2</span>−13x+40</span>
<span><span>x2</span>−13x+40=<span>x2</span>−13x+</span>
Answer:

Step-by-step explanation:
In this question, we're going to solve the equation.
What we would do is plug in the given information in the right variable. In this case, we would plugin -8 to x, since x = -8
We are solving for y, so we would nee to find how much y = ?
Your equation should look like this:

Lets solve:

When you're done solving, you should get y = 2
This means that y = 2

Given parameters:
Length of the gift box = 8 inches
Width of the box = 3 inches
Height of the box = 4 inches
Unknown :
Length of its longest diagonal = ?
Solution:
This is a rectangular box.
To find the diagonal of such box, let us use the formula below;
Diagonal = 
l is the length
w is the width
h is the height
Input the parameters and solve;
Diagonal =
= 9.4inches
The diagonal of the box is 9.4inches
Answer:
So, coordinate of intersection point = (2,0)
Explanation:
Given a triangle DCE whose coordinate of the vertex are :
D(−4, 0), C(0, −2), and E(5,3)
We will find the equation of CE
Firstly find the slope of CE
Slope (m) = 
m =
= 1
Equation of line is :
y - y₁ = m(x - x₁)
y - (-2) = 1(x-0)
y + 2 = x equation of CE
Find the intersection point of CE and x-axis
Put y = 0 to find the x-intercept
0 + 2 = x
x = 2
So, coordinate of intersection point = (2,0)
