Step-by-step explanation:
the question answer a should be
Answer:
area=πr²=3.14×4²=50.24ft²
We have,
(2y)^3 × y^-1
Simplify the term (2y)^3
= 8y^3 × y^-1
Now, multiply the terms with the same base y by adding their exponents.
Note: Using exponent product rule x^y × x^z = x^(y+z)
= 8y^{3+(-1)}
= 8y^(3-1)
= 8y^(3-1)
= 8y^2
Answer:
49
Step-by-step explanation:
when you follow the instructions and there will be k; k is constant. so t=36 so you through then k will be 1764.
Answer:
12-9x
Step-by-step explanation:
Here, we want to write an algebraic expression from the given statement
Let us start with the product of 9 and a number x
What this mean is that we want to multiply 9 and x
That gives 9 * x = 9x
Now, 12 is decreased by this product means we are to subtract 12 from it
we have this finally as;
12-9x
