Answer:
x = 2
Step-by-step explanation:
X² = 3x - 7 = 0
X² = 3x = 7
(x + 1) (x + 2) = 7
(x + 1) + x = 7 - 2
x + x = 7 - 3
2x = 4
x = 4/2
x = 2
The picture in the attached figure
let
AB=x
we know that
perimeter of the figure=10*x
perimeter=42.5 cm
so
42.5=10*x
x=42.5/10
x=4.25 cm
area of the figure=area of rectangle +area of square
area of rectangle=4.25*(4.25*3)----> 54.1875 cm²
area of square=4.25²----> 18.0625 cm²
area of the figure=54.1875+18.0625-----> 72.25 cm²
the answer is72.25 cm²
Answer:
27x-64x^2
Step-by-step explanation:
Distribute the 8x
3x-64x^2+24x
Combine like terms (3x and 24x)
27x-64x^2
