Answer:

the answer is (-256)

Step-by-step explanation:

4 to the 4 is just -4 times itself four times.

-4 times itself four times broken down is:

-4 times -4 = 16

and then

16 times -4 is -64

-64 times -4 again is

-256

Hoped this helped!

For question 1, just plug in -2 as h.

 $-2(-2)^2-(-2)+2$

You would get...

$h(-2)=-4$

Hope this helped! -4, or option 1, is correct!

The Perimeter is x+38

OLga [1]

P=x+38

add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10

set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x

then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46

sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11

Equations for height of trapezoid

devlian [24]

Answer:

$h= \frac{\sqrt{(-a+b+c+d)(a-b+c+d)(a-b+c-d)(a-b-c+d)}}{2|b-a|}$

Step-by-step explanation:

The height (or altitude) is the perpendicular distance between the bases.
In the case that the two bases have different lengths (a ≠ b), the height of a trapezoid h can be determined by the length of its four sides using the formula

$h= \frac{\sqrt{(-a+b+c+d)(a-b+c+d)(a-b+c-d)(a-b-c+d)}}{2|b-a|}$

where c and d are the lengths of the legs.
