Answer: -2x^2-12x-17
Step-by-step explanation:
-2(x+3)^2+1 Original equation
-2(x^2+3x+3x+9)+1 factor (x+3)(x+3)
-2x^2-12x-18+1 Multiply the factored part by -2
-2x^2-12x-17 Combine like terms
Answer:
1 - c
2 - A
Step-by-step explanation:
Hey There!
So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume
Remember to find the volume we use the equation
V = length x width x height
so we just plug in the values
v = 2.6 x 2.1 x 3.9 = 21.294
the closest is 20 so C is your answer
For the second one we are given a triangular prism
and they want us to find the volume

b = base (10.3)
l = length (4)
h = height (7)
7x4=28
28x10.3=288.4
then we divide by 2
288.4/2=144.2
so your selected answer is correct
Answer:
P = 12x +32
Step-by-step explanation:
The perimeter is found by using the formula
P =2(l+w)
We know the length and the width
P = 2(x+4 + 5x+12)
Combine like terms
P = 2(6x+16)
Distribute
P = 12x +32
Answer:
80 oz
Step-by-step explanation:
