Answer:
a^7
Step-by-step explanation:
=(a^3)^3/a^2
=a^9/a^2
=a^7
Answer 9
The first value behind the decimal point is 0.
When rounding if the value is 0-4 then the value you are rounding to remains the same.
If the value is 5-9 then the value would round up.
However, because it is a 0 it remains a 9.
Answer:
|(-a)²| = | a² | = a²
Step-by-step explanation:
absolute value is always positive number as well as any number squared so sign is positive no matter what
Multiply 3 times 6 times 3 to get the total number of choices.
Since there can only be one meat, one vegetable, and one cheese, the chances are 1/54.
Answer:
x = 2 or x = -5
Step-by-step explanation:
x² + 3x - 4 = 6
x² + 3x -4 - 6 = 0
x² + 3x - 10 = 0 (Here you find two numbers that have a sum of 3 and a product of -10. These two numbers would be 5 and -2. 5 - 2=3 and 5×-2 =-10.)
x² + 5x - 2x -10 = 0 (They you replace 3x by 5x and -2x)
(x² + 5x) (-2x -10) =0 - (You find common terms)
x(x + 5) -2(x + 5) = 0
(x - 2) (x + 5) = 0
So
x - 2 = 0 or x + 5 = 0
x =2 x = -5
