Answer: x2+17x+3
Step-by-step explanation:
2x2+7x−x2+10x+3
=2x2+7x+−x2+10x+3
Combine Like Terms:
=2x2+7x+−x2+10x+3
=(2x2+−x2)+(7x+10x)+(3)
=x2+17x+3
Answer:
D. Inno
Step-by-step explanation:
You can estimate cube roots by trying to get the two closest cube roots. Inno used √9 and √16. These two roots are the closest to √10. The cube root of √9 and √16 are 3 and 4 respectively, which means the √10 is between these two numbers, because √10 is between √9 and √16. √9 is the closest to √10, so the cube root of 10 is a number close to 3.
My english can be confusing but I tried :) Hope you understand it.
12 to 14=2
14 to 18=4
18 to 26=8
26 to 42=16
The difference between each number doubles each time.
Therefore the next 2 numbers should be 74 and 138.
16x2=32, 42+32=74
32x2=64, 74+64=138
