She should start on the x axis (the one that's horizontal or goes left to right) and should go to the right first. Right is positive and the first number is a positive three so she would go to the right three units first.
Get Y by itself so it' should look like this
5y=2x+7 after then you have divide 5 onto the right side and it should look like
Y=2/5x+7/5
X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides
Answer:
The answer is 88, trust.
Step-by-step explanation:
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
The length is 3x + 7
The width is 2x + 2
The perimeter is
<h3>2( 3x + 7) + 2( 2x + 2)</h3>
Simplify
6x + 7 + 4x + 4
Group like terms
6x + 4x + 7 + 4
We have the final answer as
<h3>10x + 11</h3>
Hope this helps you
