Answer: x=36°
Step-by-step explanation:
The four interior angles of a quadrilateral always equal 360°, so:
(x+16)+(4x-8)+(4x-8)+x=360
Combine like terms:
360=10x+0
360=10x
36=x
Answer:
Step-by-step explanation:
Volume = length * width * height
= (x + 1) *x *(3x + 5)
Multiply (x +1) and x
= (x*x + x*1) * (3x +5)
= ( x² + x) * (3x + 5)
= x²*(3x +5 ) + x(3x +5)
=x²*3x + x²*5 + x*3x + x*5
= 3x³ + 5x² + 3x² + 5x
= 3x³ + 8x² + 5x
First, distribute the 3/5 to get
3x+6=-24
then subtract the 6 form both sides to get
3x=-30
then divide each side by 3 to get
x=-10
Answer:
=-26
Step-by-step explanation:
f(n) = 7n – 5
Let n = -3
f(-3) = 7*(-3) – 5
Multiply first
= -21-5
=-26
