First box’s is angle addition postulate. The the second box is x=15
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>.
The answer is -60=60
Simplifying
s2 + -17s + -60 = (s + -5)(s + -12)
Reorder the terms:
-60 + -17s + s2 = (s + -5)(s + -12)
Reorder the terms:
-60 + -17s + s2 = (-5 + s)(s + -12)
Reorder the terms:
-60 + -17s + s2 = (-5 + s)(-12 + s)
Multiply (-5 + s) * (-12 + s)
-60 + -17s + s2 = (-5(-12 + s) + s(-12 + s))
-60 + -17s + s2 = ((-12 * -5 + s * -5) + s(-12 + s))
-60 + -17s + s2 = ((60 + -5s) + s(-12 + s))
-60 + -17s + s2 = (60 + -5s + (-12 * s + s * s))
-60 + -17s + s2 = (60 + -5s + (-12s + s2))
Combine like terms: -5s + -12s = -17s
-60 + -17s + s2 = (60 + -17s + s2)
Add '17s' to each side of the equation.
-60 + -17s + 17s + s2 = 60 + -17s + 17s + s2
Combine like terms: -17s + 17s = 0
-60 + 0 + s2 = 60 + -17s + 17s + s2
-60 + s2 = 60 + -17s + 17s + s2
Combine like terms: -17s + 17s = 0
-60 + s2 = 60 + 0 + s2
-60 + s2 = 60 + s2
Add '-1s2' to each side of the equation.
-60 + s2 + -1s2 = 60 + s2 + -1s2
Combine like terms: s2 + -1s2 = 0
-60 + 0 = 60 + s2 + -1s2
-60 = 60 + s2 + -1s2
Combine like terms: s2 + -1s2 = 0
-60 = 60 + 0
-60 = 60
Solving
-60 = 60
