sqrt(10x)*sqrt(8x) = sqrt(80x2) = sqrt(16x2*5) = sqrt(16x2)*sqrt(5) = 4x*sqrt(5)
12
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
-10x-6 = -12 -10x = -12+6 -10x = -6 x = 3/5
10x-8 = 2
120 square feet. This is an easy calculation - just multiply the length by the width. The answer is the number of square feet.
Length times width gives you the answer, surely you can do 10X 12 in your head....
√(10x) * √(8x) = √(80x²)√(80x²) = √(16x²) * √(5) = 4x*√(5)■
90 square meters
9 needs to be added to complete the square. When squaring (x + n), the result is x2 + 2nx + n2. We have +10x, so n must be 10/2 = 5. Thus: (x + 5)2 = x2 +10x + 25 = x2 +10x + 14 + 9 So 9 needs to be added to complete the square, giving: x2 +10x + 14 = (x + 5)2 - 9
25
Any dimension that H*W*D =5000 The room could be 1 ft * 1 ft * 5000 ft or 10 ft * 20 ft * 25 ft.
sqrt(10x)*sqrt(8x) = sqrt(80x2) = sqrt(16x2*5) = sqrt(16x2)*sqrt(5) = 4x*sqrt(5)
Twenty-Five x2 + 10x = 8 x2 + 10x + 25 = 8 + 25 (x + 5)2 = 33
You never square a whole equation. That's just silly.
