80x Each member is 8 (not 80) times the previous one.
√(10x) * √(8x) = √(80x²)√(80x²) = √(16x²) * √(5) = 4x*√(5)■
It's an equation. If you're looking for the value of x, you can solve it like this: x + 3 = 80x + 4 x = 80x + 1 -79x = 1 x = -1/79
If: y = 20 -x and x^2 +y^2 = 80 Then: x^2 +(20-x)^2 = 80 Multiplying out the brackets: x^2 +400 -80x +4x^2 = 80 Transposing terms: 5x^2 +320 -80x = 0 Divide all terms by five: x^2 +64 -16x = 0 Factorizing: (x-8)(x-8) = 0 => x = 8 and x = 8 By substitution point of contact is at: (8, 4)
8 X 10 X x = 640ft3 80x = 640 80x/80 = 640/80 x = 8 The answer is 8 feet deep
80x+32y=1280

64x2-80x+25 = (8x-5)(8x-5) when factored
The GCF is 16x.
60x + 120x - 40x - 80x - 30x = 24030x = 240x = 240/3 = 80
90x
You have to write an equation for this. When you do percents, you always have to convert them to decimals. (Therefore, 80% is .80 as a decimal) .80x = 8 Divide both sides of the equation by .8 and you'll get x = 10
Answer: Part A: 5x^10−80x^2 Part B: 5x^2(x^4+4)(x^2+2)(x^2−2) Step-by-step explanation: Factor 5x^10−80x^2 5x^10−80x^2 This is how you would factor it =5x^2(x^4+4)(x^2+2)(x^2−2)
