288 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
f(x) = 8x - 4x2 - 5x - 36 = -4x2 + 3x - 36 The domain for f(x) can be the whole of the Complex field or any subset.
Suppose the height is 15x cm. Then the width is 8x cm. Then the surface area is 2*(15x*8x + 8x*22 + 22*15x) cm2 Therefore 2*(15x*8x + 8x*22 + 22*15x) = 2506 or 15x*8x + 8x*22 + 22*15x = 1253 120x2 + 506x - 1253 = 0 so that x = -529/30 or 13/4 But x cannot be negative so x = 1.75. Therefore, volume = (15*1.75)*(8*1.75)*22 = 8085 cm3
It is: x = 4.5 and so the acute angles are 36 degrees and 54 degrees
y=-2x^2+8x+3
By implication : x2-8x+7 = kx-2 Form a quadratic equation: x2-8x-kx+9 = 0 For a line to be a tangent to the curve it must have two equal roots and the discriminant b2-4ac of the quadratic equation must equal 0. So: (-8-k)2-4*1*9 = 0 (-8-k)2-36 = 0 (-8-k)2 = 36 Square root both sides: -8-k = -/+6 -k = 2 or 14 k = -2 or -14 When k = -2 is substituted into the quadratic equation x will have two equal roots of 3 When k = -14 is substituted into the quadratic equation x will have two equal roots of -3
Area_triangle = base x height x 1/2 ⇒ 36 = (8x) x 4 x 1/2 ⇒ 8x = 18 ⇒ x = 21/4 (= 2.25)
8x-36 equal = -28
The square root of 8x can be simplified as √8x = √(4*2x) = 2√2x. This is because we can break down 8 into 4 and 2, and since the square root of 4 is 2, we can pull it out of the square root. Therefore, the simplified form of the square root of 8x is 2√2x.
The square root of (8x^2) can be simplified by breaking it down into its components. The square root of (8) is (2\sqrt{2}), and the square root of (x^2) is (x). Therefore, the square root of (8x^2) is (2x\sqrt{2}).
To solve for x in the equation -8x + 4 = 36, you first need to isolate the variable x. Start by subtracting 4 from both sides of the equation to get -8x = 32. Then, divide both sides by -8 to find x. Therefore, x = -4.
√(10x) * √(8x) = √(80x²)√(80x²) = √(16x²) * √(5) = 4x*√(5)■
The GCF of 8x and 12x2 is 4x.
length = 56 with = 48Improved Answer:Presumably your question is about finding the dimensions of a rectangle?If so then let the length be (x+8) the width be x and the square be x2:(x+8)*x = x2+160 square feetx2+8x = x2+160x2-x2+8x = 1608x = 160x = 20Therefore: length = 28 feet and width = 20 feetCheck: 28*20 = 400+160 = 560 square feet
f(x) = 8x - 4x2 - 5x - 36 = -4x2 + 3x - 36 The domain for f(x) can be the whole of the Complex field or any subset.
5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12
5x - 4 + 3x = 36 Simplify: 8x - 4 = 36 Add 4 to both sides: 8x = 40 Divide both sides by 8: x = 5
It can be simplified to: -14x-36
