Question

isosceles 7 X + 3 5x + 7

Answer 1

Hey there!

If your problem looks like:$(7x$$+3)$ $(5x$$+7)$

You have to $distribute$ the equation, so

$7x$$(5x)$ $+$ $7x$$(7)$$+$ $3$$(5x)$  $+$ $3(7)$

$Simplify$ the $equation$ out

$7x$$(5x)$ $=$ $35x^2$

$7x$$(7)$  $=$ $49x$

$3$$(5x)$ $=$ $15x$

$3(7)$ $= 21$

$Combine$ your $like$ $terms$

$49x$ $+$ $15x$ $=$ $64x$

Therefore your $\boxed{answer}$ is:

$35x^2$ $+$ $64x$ $+$ $21$

Good luck on your assignment and enjoy your day!
