Answer: 2a^2+22a+−1
Step-by-step explanation:
Let's simplify step-by-step.
2a^2−5a+(9)(3)a−1
=2a^2+−5a+27a+−1
Combine Like Terms:
=2a^2+−5a+27a+−1
=(2a^2)+(−5a+27a)+(−1)
=2a^2+22a+−1
Answer:
48
Step-by-step explanation:
Double the product of 4y and 3b
2 * ((4y) * (3b))
y = 2 and b = 1
2 * ((4 * 2) * (3 * 1))
2 * (8 * 3)
2 * 24
48
Answer:
16
Step-by-step explanation:
3x-2x=8
x=8
QR=8*2=16
see the attached figure to better understand the problem
Step 1
<u>Find the number of pages printed on an Apricot printer </u>
we know that
The speed of an Apricot printer is 8ppm
so
in 4.5 min
Carlos print
4.5*8=36 pages
step 2
<u>Find the time it takes Carlos to print the same amount of documents on a sure fire printer printer</u>
we know that
The speed on a sure fire printer is 12ppm
so
Divide the total of pages by the speed of the printer
36/12=3 minutes
therefore
<u>the answer is</u>
3 minutes
