Answer:
C
Step-by-step explanation:
If you would like to write a * b + c in simplest form, you can do this using the following steps:
a = x + 1
b = x^2 + 2x - 1
c = 2x
a * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1
The correct result would be x^3 + 3x^2 + 3x - 1.
Answer:
Do the parentheses first. then the operations. Then solve
Step-by-step explanation:
Across smallest side- smallest angle.
across largest side- largest angle
largest side is AC, so largest angle is B
smallest side is AB, so smallest angle is C
angles from smallest to largest : C, A, B
Answer: Find the GCD (or HCF) of numerator and denominator. GCD of 70 and 20 is 10.
70 ÷ 1020 ÷ 10.
Reduced fraction: 72. Therefore, 70/20 simplified is 7/2.
