Answer:
350 cm2
Step-by-step explanation:
use the formula 2h ( l+b)
Answer: 2 + √10 , 2 − √10
Step-by-step explanation:
-5x(x-4) = -30
divide by -5
x(x - 4) = -30
distribute the x
x^2 - 4x = 6
move the 6 to the left to have the equation equal zero
x^2 - 4x - 6 = 0
plug into the quadratic formula & solve
x
= 2 + √10 , 2 − √10
Answer:
x = 3/4
Step-by-step explanation:
Simply add 1/4 to both sides of the equation to isolate <em>x</em> and to get your answer.
x = 1/4 + 1/2
x = 1/4 + 2/4
x = 3/4 or 0.75
27/4
4*6=24
27-24=3
remainder is 3
