Answer:

32y² + 192y

Step-by-step explanation:

First, we need to distribute 8y. This gets us 32y²+192y. I do not believe you can simplify that. I hope this helps!

What is the y-intercept of a line that has a Slope of 3 and passes through point (-1, -7)

Degger [83]

Answer:

B)-4

Step-by-step explanation:

y=mx+c

sub in a point and gradient/slope to get c

-7=3(-1)+c

-7=-3+c

-7+3=c

c=-4

y=3x-4

if u looking for the y intercept make x=0

y=3(0)-4

y=-4

The perimeter of Stephanie’s triangle is half the perimeter of Juan’s triangle. Juan’s triangle is shown. Write a numerical expr

denpristay [2]

The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: $\frac 12 \times 25$

Let the sides of Juan's triangle be x, y and z. So:

$x = 5 \\ y = 8\\ z = 12$

The perimeter (J) of Juan's triangle is calculated by adding all sides.

So:

$J =x +y +z$

This gives:

$J =5 + 8 + 12$

$J =25$

From the question, we understand that:

The perimeter (S) of Stephanie's triangle is half that of Juan.

This means that:

$S = \frac 12J$

Substitute 25 for J

$S = \frac 12 \times 25$

Hence, the numerical expression for the perimeter of Stephanie's triangle is: $\frac 12 \times 25$
