Answer:
B. He added 5 to each side of the equation.
Step-by-step explanation:
B. He added 5 to each side of the equation.
h = 
multiply both sides by 2 to eliminate the fraction
2A = ( b + c)h
isolate h by dividing both sides by (b + c)
h =
Answer:
2 inches
Step-by-step explanation:
Snail C moves 1 inch every 15 mins. Since half an hour is 30 mins, 30 / 15 = 2.
15 mins + 15 mins = there for your answer is 2 inches in half an hour.
Answer:
(- 2, 0 ), (1, 0 )
Step-by-step explanation:
Given
y = 2x² + 2x - 4
To find the x- intercepts let y = 0, that is
2x² + 2x - 4 = 0 ← divide through by 2
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Thus x- intercepts are (- 2, 0) and (1, 0)
