There is 100% in 1 since this is three parts of 1 we will have to divide 100 by 4 then multiply it by 3.
After you do all the math you will get 0.75.
You can convert this to a percent by just removing the point and the zero and adding a percent at the end.
The answer is going to be 75%
Yes square meters is a type of surface area.
Answer:
49x² + 42x + 9
Step-by-step explanation:
Given
(7x + 3)²
= (7x + 3)(7x + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
7x(7x + 3) + 3(7x + 3) ← distribute both parenthesis
= 49x² + 21x + 21x + 9 ← collect like terms
= 49x² + 42x + 9
ANSWER
Vertex form:

Vertex
V(-4,-11)
EXPLANATION
The given expression is

We complete the square to get the vertex form.
Add and subtract half the square of the coefficient of x.


The vertex is
V(-4,-11)
