Answer: 112

Step-by-step explanation:

Since we were given m and n, we plug them into the expression and solve.

-2(-6)+4(-5)²            [exponent]

-2(-6)+4(25)            [multiply]

12+100                     [add]

112

Now, we know that the value of the expression is 112.

makkiz [27]

Answer: The two sides are 15m and 10m.

Step-by-step explanation:

Area = l x w

150 = l x w

There are two solutions for l

l 1= P/4+1/4√P2﹣16A

=50/4+1/4·√50^2﹣16·150=15m

l2 = P/4﹣1/4√P2﹣16A

=50/4﹣1/4·√50^2﹣16·150=10m
