I assume by "x -2" is on the rectangle you mean the length of the rectangle is x - 2. So If I understand the question correctly, then: P = 2L + 2H 44 = 2(2 +x) + 2(6) 44 = 4 + 2x + 12 44 - 16 = 2x 28...

Algebra sloping (answer)

Yes. A slope does exist. Slope is just "Rise over run". (y1 - y2) / (x1 - x2) = m This can also be expressed as: m = Δy / Δx (slope equals Delta y over Delta x [Delta is commonly used to represent "the change in".]) So... plug in the...

Perimeter = Sum of the length of the sides. Sense we're dealing with a square, all sides are equal. Therefore, the perimeter of the square would be: 4 + 4 + 4 + 4 = 4 * 4 = 16. 16 cm.

Work with Functions (answer)

If I understand the question correctly - you're looking for a formula to express a graph going through the listed points. Okay... if you plot this on a graph it looks to have a slope of 1/1 (that is, for every one it moves over via 'x' , it moves up one. When x = 0, y = 7, so we know we have...

(5-z)/z = 9 Multiply both sides by "z". (5-z)/z*z = 9z 5-z = 9z Put the variable on one side. 10z = 5 z = .5 Do I need to break it down further?

l=3w-2 l*w=21 (3w-2)*w=21 3w2-2w=21 3w2-2w-21=0 We can now apply the quadratic formula: (-b +/- SQRT(b2 - 4ac))/2a plug in the values: (-(-2) + SQRT((-2)2 - 4(3)(-21))/2(3) (2 + SQRT(4 + 252))/6 = x (2 + 16)/6 = x 18/6 = 3 x = 3 w...

need formula to find out how many yards of concerte to order for my patio it is 15 x 11x 4in thick (answer)

Sounds like a volume problem to me. Calculate the total volume of the patio. Convert units. V = L x W x H 123in3 = 1 ft3 33ft3 = 1 yd3
