When you multiply 13 by 64 you will get 832. You may need a calculator or a mathematical table to perform this operation. You may also use an online calculator to perform this task
1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832:1 x 832, 2 x 416, 4 x 208, 8 x 104, 13 x 64, 16 x 52, 26 x 32
x2 - 10x + 25 = 64 Or x2 - 10x + 25 = 64? If the first, move all over to 1 side; x2 - 10x + 25 - 64 = 0 x2 - 10x + -39 = 0 Then make it into quadratic equations; (x - 13)(x + 3) = 0 Therefore x = 13 or x = -3. If the second, 8x = -39 -39/8 = -9.75 = x
Equation: 8x^2 -26x +15 =0 I Divide all terms by 8: x^2 -26/8 +15/8 = 0 and complete the square as follows:- (x -13/8)^2 -169/64 +15/8 = 0 => (x-13/8)^2 = 49/64 Square root both sides: x-13/8 = -/+ 7/8 Add 13/8 to both sides: x = 13/8 -/+ 7/8 Therefore solutions are: x = 5/2 or x = 3/4

3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
16 x 4 = 64 77 - 64 = 13 4 times with 13 remaining
Using the vertex (h, k) the equation of the quadratic would be: y = a(x - h)² + k → y = a(x - 8)² + 2 → y = a(x² - 16x + 64) + 2 → y = ax² -16ax + 64a + 2 Using the y-intercept of (0, -11): -11 = a 0² - 16a 0 + 64a + 2 → 64a = -13 → a = -13/64 Thus the quadratic could be: y = (-13/64)x² - 16(-13/64)x + 64(-13/64) + 2 → y = (-13/64)x² + (13/4)x - 11 Or, removing the fractions: 64y = -13x² + 208x - 704

You find numbers that divide evenly into 64, such as for example, 1, 2, 4, 8, 16, 32, and 64. Then sharpen your pencil and start writing. 1 x 64 = 64 2 x 32 = 64 4 x 16 = 64 8 x 8 = 64 2 x 2 x 16 = 64 2 x 4 x 8 = 64 4 x 4 x 4 = 64 2 x 2 x 2 x 8 = 64 2 x 2 x 4 x 4 = 64 2 x 2 x 2 x 2 x 4 = 64 2 x 2 x 2 x 2 x 2 x 2 = 64
The first ten positive integer multiples of 64 are:1 x 64 = 642 x 64 = 1283 x 64 = 1924 x 64 = 2565 x 64 = 3206 x 64 = 3847 x 64 = 4488 x 64 = 5129 x 64 = 57610 x 64 = 640

These numbers multiply to equal 832: 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 8321 x 832, 2 x 416, 4 x 208, 8 x 104, 13 x 64, 16 x 52, 26 x 32
8 x 8 = 64 32 x 2 = 64 63 + 1 = 64 100 - 36 = 64
