Answer:
4ab² + 20b - 3a
Step-by-step explanation:
This question most likely asks us to simplify the expression, as factoring is not possible...
(ab² + 13b - 4a) + (3ab² + a + 7b),
ab² + 13b - 4a + 3ab² + a + 7b,
ab² + 3ab² + 13b + 7b - 4a + a,
Solution : 4ab² + 20b - 3a
Slope = Y2-Y1/X2-X1 = 7-(-3)/3-(-2)= 10/5 = 2
x= r - h/y subtract r from both sides
x-r = -h/y multiply each side by -y
-y(x-r) = h
-xy +yr = h
Answer:
<h3>x = 40/7</h3>
Step-by-step explanation:
Look at the picture.
If ABC is any triangle and AD bisects (cuts in half) the angle BAC, then

In our triangle we have the proportion:
<em>cross multiply</em>
<em>use distributive property</em>

<em>add 8x to both sides</em>
<em>divide both sides by 14</em>
