Answer:
you add them, but keep the sign
Step-by-step explanation:
Square root.
5^2 = 25 so sqrt25 = 5
Answer:
See below.
Step-by-step explanation:
Angle: 180-132 = 48
180-48= 132
132/6=22
2(22)= 44
4(22)= 88
44+88+32 = 180
Answer:
Measure of angle < CBA = 88
Measure of angle < BCA = 44
Answer:
у = x² + 7x - 30
Step-by-step explanation:
x₁ = 3 and x₂ = -10
Use the formula (x - x₁)(x - x₂) = 0
(x - 3)(x - (-10)) = 0
(x - 3)(x + 10) = 0
x² + 10x - 3x - 30 = 0
x² + 7x - 30 = 0
