Answer:
30 feet
Step-by-step explanation:
a = l * w
Its a square so l and w are the same
x * x = 900
30 * 30 = 900
----------------
If you know about square roots
x = √900
x = 30

Answer: x = 18 (choice B)</h3>
===================================
Work Shown:
Through the inscribed angle theorem, we can say that 2 times the inscribed angle gets us the arc that the inscribed angle cuts off.
2*(inscribed angle) = arc measure
2*(2x+2) = 76
4x+4 = 76
4x+4-4 = 76-4 ... subtract 4 from both sides
4x = 72
4x/4 = 72/4 ... divide both sides by 4
x = 18
Answer:
x^2 + x - 72 = 0
Step-by-step explanation:
x(x + 1) = 72 should be re-written in the standard form of a quadratic:
x^2 + x - 72 = 0. Same as the first answer choice.
(-2,2)(2,-8)
slope = (-8 - 2) / (2 - (-2) = -10/4 = -5/2
y = mx + b
slope(m) = -5/2
(-2,2)...x = - 2 and y = 2
now we sub and find b, the y int
2 = -5/2(-2) + b
2 = 5 + b
2 - 5 = b
-3 = b
so ur equation is : y = -5/2x - 3
Answer:
3 square inches
Step-by-step explanation:
So you would multiply 3*3*3*3
All the sides of the window 4 3's
3*3=9*3=27*3=81
So therefore your answer is 3 square inches
