The way to do this is get an expression equal to zero, then solve (in this case it's a quadratic), so either factor or use the quadratic equation. x2 + x - 56 = 0: Factors into: (x - 7)(x + 8) = 0, x = 7 & x = -8
To factor, find two numbers which when added equal 1 (the coefficient of the x term) and when multiplied equal -56. So one of the numbers must be positive and the other negative. Factor pairs of 56 are (1,56) (2,28) (4,14) and (7,8). Seven & eight are one apart, so if the seven is negative, they will add to equal 1. If either of the binomial factors is zero, then the result is zero, so for (x-7)=0, {x=7} solves it, and for (x+8)=0, {x=-8} solves it. Check your answers in the original equation, to make sure you did it correctly:
7^2 + 7 = 49 + 7 = 56 (check) (-8)^2 + -8 = 64 - 8 = 56 (check) STANLY WAS HERE
(X +7) X-8)
56
7x = 56 To find the solution for x, you should divide both sides of the equation by 7 to get x = 8.
72 minus the root of squared minus equals 72 but you have to be smart to know that the minimum circumference s 56 there you go
56
If the equation is (5x + 3 - 7) / 2 = 56, than x = 23.2
a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
The answer is 7. Seven squared is forty nine. 49 plus 7 equals 56.
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
The solution follows A=42 42X42=1764 B=56 56X56=3136 sum of above=4900 (70X70=4900) Given you was looking for C and not C squared. Try A and B and doublecheck it for me.

56 plus zero
First you must square the 6 which the answer is 36. Then you subtract 36 from 8 and the answer is negative 28. Finally you solve negative 28 minus 28 (-28-28) which equals negative 56 (-56).
56 plus 1 equals 57. == ==
1 + 2 + 56 = 59
x - 56 = 79 x - 56 + 56 = 79 + 56 x = 135
If by area you mean X*Y it would be -49 (or 49, if you assume area to be positive). (X=7, Y=-7) when X+Y^2=56 and X+Y=0.
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
