Answer:
-3x+2
Step-by-step explanation:
Since it's addition you just combine all like terms so,
5x+4
-8x-2
= -3x+2
Answer:
3.5325
Step-by-step explanation:
V = 3.14*(.75^2)(2)
You divide the diameter by 2 to get the radius which is 1.5/2 =.75
r=.75
h=2
and you use the equation for volume of cylinder which is V = pi x radius squared x height
A. -3x+5+7-4x
-3x-4x+5+7
-7x+12
-7x+12-5x+17
-7x-5x+12+17
-12x+29
B. -5*(x+2)= -5x-10
-6x-1+ (-5x-10)= -6x-5x-1-10=
-11x-11
Answer: 32/20 or 8/5
Step-by-step explanation: Turn 7/5 into 28/20. Do 28/20 plus 4/20. That equals 32/20 or 8/5.
Answer:
f(-2) = 5
Step-by-step explanation:
To find f(-2), plug in -2 wherever there is an x.
f(x) = 4x² + 3x - 5
f(-2) = 4(-2)² + 3(-2) - 5
f(-2) = 4(4) + 3(-2) - 5
f(-2) = 16 - 6 - 5
f(-2) = 10 - 5
f(-2) = 5
