Your answer is A 0.8 hope it helps:)
√5(√10 + √3) = √(5 · 10) + √(5 · 3) =
= √50 + √15 = √(25 · 2) + √15 =
= √(5² · 2) + √15 = 5√2 + √15 ← the end
Answer:
x = 10
Step-by-step explanation:
-8(-3 + x) = -56
Distribute the -8 into the (-3 + x).
24 - 8x = -56
Subtract 24 from both sides.
-8x = -80
Divide both sides by -8.
x = 10.
Proof:
-8(-3 + x) = -56
Substitute variable.
-8(-3 + 10) = -56
Add inside parenthesis.
-8(7) = -56
Multiply.
-56 = -56
all even numbers
hope it really helps...!!!
Answer:
x = 0, x = - 3
Step-by-step explanation:
Given
5x² - 7x = 4x² - 10 ← subtract 4x² - 10x from both sides
x² + 3x = 0 ← in standard form
Factor out x from each term
x(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x + 3 = 0 ⇒ x = - 3
