Step-by-step explanation:
<u>Step 1: Define</u>
2x + 4y = 24
y = -3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>: 2x + 4(-3) = 24
- Multiply: 2x - 12 = 24
- Isolate <em>x</em> term: 2x = 36
- Isolate <em>x</em>: x = 18
The answer is D.(1,-1) the reason is -1(y)-2*1(x)=-3 so, -1-2*1 is less than or equal to -3.
Answer:
11 feet
Step-by-step explanation:
Given,
Area of square ( a^2 ) = 121 ft
To find : Length of each side ( a ) = ?
Formula : -
Area of square = a^2
a^2 = 121
a = √121
a = 11 feet
