(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
y=7+x =x=7-x
If (x + 3)(x +7) = 0 then either: x + 3 = 0 or x + 7 = 7 Hence x = -3 or -7.
x/35 =7 (x/35) *35 = 7 * 35 {multiply both sides by 7} x = 7 * 35 x = 245
It is f(x) = 7/x.
575 + 7% = 575 x (1 + (7/100)) = 575 x 1.07 = 615.25
1, 5, 7, 23, 25, 35, 115, 161, 175, 575, 805 and 4,025 as follows:1 x 4025, 5 x 805, 7 x 575, 23 x 175, 25 x 161, 35 x 115
Use a factor tree. 575 115,5 23,5,5 5 x 5 x 23 = 575
5 x 115 = 575

.16 x 575 = 92. 16 percent of 575 is 92.
575 = 52 x 231
575 x 1.3 = 747.5
575 hours is 34,500 minutes. (60 minutes per hour x 575 = 34,500)
575 :)
(100 X 112)/575 = 19.5 %, to the justified number of significant digits.
