Answer:
Step-by-step explanation:
(x +y)² = x² + 2xy +y²
-5(x + 3)² = -80
-5(x² + 2*x*3 + 3²) = -80
-5(x² + 6x + 9) = -80
Divide the equation by (-5)
x² + 6x +9 = -80/-5
x² + 6x + 9 = 16
x² + 6x + 9 - 16 = 0
x² + 6x - 7 = 0
x² - x + 7x - 7 = 0
x(x - 1) + 7(x - 1) = 0
(x - 1)(x + 7) = 0
x -1 = 0 ; x + 7 = 0
x = 1 ; x = -7
Answer:
Option B
Step-by-step explanation:
x^3
Coefficient = 1
Option B
Step-by-step explanation:
we can find the length of other side by hypotenuse formula,
which is h² = a² + b²
so,
a = 157
b = 168
now after inserting the values we got,
→ h² = (157)² + (168)²
→ h = 24649 + 28224
→ h = 52,873
→ h² = √52873 = 229.94
so, length of other side is 229.94
