Answer:

x = 14

Step-by-step explanation:

3x/-8 = -21/4

(3x/-8)×-8 =( -21/4)×-8

3x = 42

3x/3 = 42/3

x = 14

hope it's helpful

Answer:

x = 14

Step-by-step explanation:

to solve this you have to first move 3/-8 to the other side and divide while keeping x on the same side.

now to divide you must flip over 3/8 and multiply so 21/4 x 8/3 ( negative sign cross off because there are two of them) so 3 and 21 cross off leaving 7 in the numerator 4 and 8 cross of leaving 2 in the numerator and then 7 and 2 get multiplied and you will get 14.

The figure shown is made up of triangle ABF and rectangle BCDE. The area of the figure is 90 square feet. If AB=BC=BF=FE, find A
Ludmilka [50]
The complete question in the attached figure

let
x-----> distance AB
so
AC=2x

we know that
area of the figure=area of triangle+area of rectangle
area of the figure=90 ft²

step 1
 find the area of triangle
A=b*h/2
b=x
h=x
so
A=(x*x)/2
Area of triangle=x²/2 ft²

step 2
find the area of rectangle
A=b*h
b=2x
h=x
A=(2x)*x------\ \textgreater \  A=2x^{2}
area rectangle=2x²

step 3 
find value of x
area of the figure=(x²/2)+2x²
area of the figure=90 ft²
90=(x²/2)+2x²-----> multiply by 2 both sides----> 180=x²+4x²
5x²=180-----> x²=36-----> x=6 ft

AC=2x-----> AC=2*6----> AC=12 ft

the answer is
AC=12 ft
