I hope I am thinking of the correct "equation"
I hope this helps!
Answer:
4800cm²
Step-by-step explanation:
20x30x8=4800
2x-4=(x-2)(x+2)
2x-4 =x^2-4
0=x^2-2x
0=x(x-2)
So
X=0 or x=2
8 divided by 12 is about .67
the degrres fell .67 in 1 hr
Step-by-step explanation:
(12)(2) = 24 Find 2 numbers whose product is 24 and whose sum is 11 (8 and 3 work)
Rewrite 11x as 8x+3x and factor by grouping:
12x2 + 8x + 3x + 2 = 0
4x(3x+2) + 1(3x+2) = 0
(3x+2)(4x+1) = 0
x = -2/3 or x = -1/4
