8x because everything else is addition or subtractionZ
Answer:
Step-by-step explanation: Plug -4 in for each "y" in the equation. Then solve: -4 squared is 16, 5 times -4 is -20, so you have 16-20+7 which equals 3.
Step-by-step explanation:
you don't know how exponents work ?
the exponent simply says how often the base value has to be multiplied by itself.
e.g. 5³ = 5×5×5 = 125
and when it says x=2, then you need to put 2 at every location, where is says "x".
so,
x⁵ for x = 2 means 2⁵ = 32
8² = 64
2⁴ = 16
Just remember that vertical angles are congruent and have same degree. Straight lines add up to 180 degrees.
G = 115 degrees (vertical angle)
K = 131 degrees (vertical angle)
h = 180-115 = 65 degrees
m = 180 - 131 = 49 degrees
Answer:
b. 10x^3 - 6x^2 - 9x + 12
Step-by-step explanation:
A cubic expression has the highest power of the variable to the third power
x^3
b. 10x^3 - 6x^2 - 9x + 12
is the only expression that has the highest power as x^3
a has x^4 and c and d do not have an x^3 term
