4x² - 30 = 34 4x² = 34 + 30 4x² = 64 4x = √64 4x = 8 x = 8 ÷ 4 x = 2

Let the number be x: 4x+29 = 93 4x = 93-29 4x = 64 x = 16

If [ x = -8 ], thenx2 - 4x + 9= (-8)2 - 4(-8) + 9= 64 + 32 + 9= 105

-64 is 12 more than 4 times a number...-64 equals 12 plus 4 times an unknown number...sounds like an equation to me:-64 = 12 + 4x-64 -12 = 12 + 4x - 12-76 = 4x-76/4 = 4x/4-19 = xThe number you're looking for is -19.

x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72

3/4x = 16 (multiply both sides by 4x)3 = 64x (divide both sides by 64)3/64 = x

The answer is 64.

8x + 23 + 4x - 7x = 64; Find X To make this easier, add like terms: (8x + 4x - 7x) + 26 = 64 Use the order of operations: (12x - 7x) + 26 = 64 5x + 26 = 64 -26 -26 5x = 38 5 5 Finally: x = 7(3/5)

64 is the cube of 4 so: x3 + 64 = (x + 4)(x2 - 4x + 16)

57 + 7 = 64

162+64=226
