Answer:
x=6
Step-by-step explanation:
The sum of the angles is a right angle, which is 90 degrees
5x+ x+54 = 90
Combine like terms
6x+54 = 90
Subtract 54 from each side
6x+54-54 = 90-54
6x = 36
Divide each side by 6
6x/6 = 36/6
x= 6
<span>If QRST is a rectangle with QT = 50 and RS = 4x + 8, find x.
.
QT = RS (opposite sides of a rectangle are equal)
50 = 4x + 8
42 = 4x
10.5 = x</span>
20000+6000=26000 hope it helps
Area of rectangle = length x width
6 x 3 = 18
area of triangle = base x height over 2
2 x 6 = 12
12 / 2 = 6
triangle 2
3 x 3 = 9
9 / 2 = 4.5
add everything together
4.5 + 6 + 18 = 28.5 m^2
-3^2 = (-3)(-3) = 9 (because a negative times a negative is a positive)
