Answer:

4p² -18p + 8

Step-by-step explanation:

 = (4p - 2) (p-4)

 = p (4p - 2) -4 (4p - 2)

Factor with steps please!!!
myrzilka [38]

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>

Complete the solution of the equation find the value of Y when X equals -8.<br><br> 4x+9y=-14
lukranit [14]

Answer:

\large\boxed{y=2}

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:

4(-8)+9y=-14

Lets solve:

4(-8)+9y=-14\\\\\text{Multiply}\, 4(-8)\\\\-32+9y=-14\\\\\text{Add 32 to both sides}\\\\9y=18\\\\\text{Divide}\\\\y=2

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

This means that y = 2

A gift box is 8 inches long, 3inches wide, and 4inches tall. What is the approximate length of its longest diagonal?A? 9.4inches
Doss [256]

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  = \sqrt{l^{2} + w^{2} + h^{2}   }

l is the length

w is the width

h is the height

Input the parameters and solve;

           Diagonal  = \sqrt{8^{2} + 3^{2} + 4^{2}   }   = 9.4inches

The diagonal of the box is 9.4inches

Construct the triangle dce using as coordinates of its vertices points d(−4, 0), c(0, −2), and e(5,3). Find the coordinates of i
Naily [24]

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) = \frac{y_{2} - y_{1}  }{x_{2} - x_{1}}

m = \frac{3-(-2)}{5-0} = 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)
