Solve this equation. -4(p+2)+8=2(p-1)-7p+15

ratelena [41]

Hey there!

First we have to $distribute$ !

$-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\ -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15$

Now, we have to $combine$ our like terms

$-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15 
$

Once we solve all the $like-terms$ we get

$-4p = 5p +13$

Now, we have to $add$ $5p$ to each of your sides

$-4p + 5p \\ = -5p + 13 + 5p$

Solve that part of the equation

$p= 13$

Good luck on your assignment and enjoy your assignment

Factor Trinomials (a=1)<br> factor <br><br> x^2-10x+16

dem82 [27]

Answer:

(x-8)(x-2)

Step-by-step explanation:

factors of 16:

1 x 16

2 x 8

4 x 4

i'll select 2 and 8 as values because they can add up to 10

(x-8)(x-2)

i made them both negative so the middle term would be -10 but, when multiplied, would equal positive 16

Find the distance between (1, 3) and (-2, -6) and put it in simplest radical form

GarryVolchara [31]

Answer:

$\tt 9.48$

Step-by-step explanation:

(1,3) and (-2,-6)

$\tt Distance= \sqrt{(-6-3)^2+(-2-1)^2}$

$\tt =\sqrt{9^2+3^2}$

$\tt =\sqrt{81+9} =\sqrt{90}$

$\tt Distance=\sqrt{90} =9.48$
