x = 8
You do the multiplication first and then the subtraction, So . . . -32 x 4 = -128 then -128 - 8 = -136 The answer is -136
is/of=%/100 58.88/x=32/100 Cross products 58.88 * 100=32x 5888=32x 5888/32=32x/32 184=x

Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16
13X squared + 7X + 12
x2+7x-8 = (x-1(x+8)
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
x2+7x-8 = (x-1(x+8)
-16x2 + x + 8 = -1/64(32x - 1 - √513)(32x - 1 + √513)
x2 + 7x - 8 = (x + 8)(x - 1)
x2+7x-8 = (x-1(x+8)
7x + 8 = 36 Therefore, 7x = 28 x = 28/7 x = 4
7x/4 = 1/8 (7x/4) x (8) = (1/8) x (8) 14x = 1 x = 1/14
Assuming that what you're looking for is the values of x: x2 + 7x = 8 x2 + 7x - 8 = 0 (x + 8)(x - 1) = 0 x is equal to either -8 or 1.
