Answer:
2x³+17x²+25x-50
Step-by-step explanation:
Standard Form: All your numbers and variables in order of the highest exponent.
(2x²+7x-10)(x+5)
We want to distribute x and 5 to every single value.
2x³+7x²-10x+10x²+35x-50
Simplify.
2x³+17x²+25x-50
This is standard form because the highest values are on the left (x³ is larger than x²).
Answer:
7
Step-by-step explanation:
formula for circumference of a circle is
d
7
=
d
d = 7
Sixty four
6 tens 4 ones
64 ones
60+4
8 to the power of 2
No matter where the negative sign is, the product will always be negative, so is the number itself.
13.2(-8.1)=-106.92
twice of that would be -213.84.
first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).
