To evaluate the expressions, you substitute -9 for x and 3 for y into the expressions
(4y)^2 - (2x)
= (4(3))^2 - (2(-9))
= (12)^2 - (-18)
= 144 + 18
= 162
4y^2 - 2x^2
= 4(3)^2 - 2(-9)^2
= 4(9) - 2(81)
= 36 - 162 = -126
Answer:
x^2 +x+2
Step-by-step explanation:
f(x) = x^2+3
g(x) = x-1
f(x)+ g(x) = (f+g) (x)
x^2+3+ x-1
x^2 +x+2
The exterior angle theorem states that an exterior angle is equal to the sum of its remote interior angles.
With that we know...
m<QRS+m<RSQ=m<SQP
90+34=x+72
124=x+72
x=52 degrees
answer: 52 degrees
Answer:
x = 2
Step-by-step explanation:
To start, you want to isolate x.
To do so, get all the x terms to one side.
2x + 1 = 4x - 3
Subtract -4x on both sides.
-2x + 1 = -3
Then, subtract 1 on both sides.
-2x = -4
Finally, divide -2 on both sides.
x = 2
