Answer:
Step-by-step explanation:
To find the value of x, using Pythagorean theorem.
7) x² = 12² + 12²
= 144 + 144
= 288
x = √2*12*12
x = 12√2
8) x² + 9² = 18²
x² + 81 = 324
x² = 324 - 81
x² = 243
x = √3*9*9
x = 9√3
Answer: X=6
Step-by-step explanation:
Solve for x
by simplifying both sides of the equation, then isolating the variable.
Answer: 34 meters.
Step-by-step explanation;
Step One. Find the value of the width. Use an equation with w representing the width and the two values you already have. 9 meters x w = 72 square meters.
Step Two. Solve for width. This is w = 8.
Step Three. Use the value for width in a perimeter formula to calculate the perimeter; 9(2) + 8(2). <em>This is 34 meters for perimeter</em>.
