Step-by-step explanation:
14 x 8 = 112
Answer:
Step-by-step explanation:
(2x^2 + 10x + 7x + 35) - (x^2 - 3x + 5x - 15)
x^2 + 15x + 50
(x + 5)(x + 10)
x = -10

Answer:
9√xy^2
Step-by-step explanation:
according to the rule of law of indices, 3√xy=xy^(1/3) like this 9√xy^2 is the correct answer
Cos <span>θ = 0.5333
inverse cosine both sides of equation
cos⁻¹(cos </span>θ) = cos⁻¹(0.5333)
on left side, cosine cancel out
on right side use calculator in radian mode
θ = 1.0083
for the ttriangle, assuming c is the hypotenuse
pythagoras
a² + b² = c²
b² = c² - a²
b = √(c² - a²)
b = √(9² - 2²)
b = 8.77
