How do you simplify 7x×4y×2y^2
belka [17]
The answer is: 56xy³
_______________________________
Explanation:
_______________________________
Find the "like terms"; which are: 
_______________________________
"4y" and "2y<span>²"
_______________________________
The remaining term is: "7x".
_____________________________________
The problem is a "multiplication problem" :
___________________________________________
7x * 4y * </span>2y² ; so start by multiplying the "like terms" :
<span>___________________________________________
4y * 2y</span>² = 8y<span>³
____________________________________________
Then the remaining term is "7x";
        so, multiply that by our obtained value: "</span>8y³ " :
_____________________________________________
7x * 8y³  = 56xy³ ; which is our answer:

RS bisects QRT, mangleQRS = (3x + 8), and mangleSRT = (5x − 4).
Leya [2.2K]

Bisect typically means half but since we aren't given angle at the start so we can just have to solve for x.

(3x + 8) = (5x - 4)

3x = 5x - 12

-2x = -12

x = 6

Best of Luck!
