Answer:
Step-by-step explanation:
We want to find an expression that is equivalent to 
.
Since we can;t get the options, we simplify the given expression.
The reason is that, the given expression will be equivalent to the simplified one.
We combine similar terms to get:
We now expand to get:
We perform the subtraction of the last two terms to get:
We now multiply to get:
Answer:
see explanation
Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Answer:
When you input values for x, you can determine a single output for y. ... Instead, you could use f(x) or g(x) or c(x). This can ... P = 4s, as the function p(x) = 4x, and the formula for area, A = x2, as a(x) = x2. ... You read this problem like this: “given f of x equals 4x plus one, find f of 2. ... f(2) = 4(2) + 1 = 8 + 1 = 9 ... f(2) = 12 + 4 + 1.
Step-by-step explanation:
Answer:
=>1
=> 
=> Simplify:minus and minus simplify each other and so do 3 and 3
=> So were are left with 1
Thus,the answer is 1
