We know that 4 × 7 = 28
We also know that 8 is
2× 4. That means we can write 8×7 as 2×(4×7). We already know that
4 × 7 = 28 so 2×28 = 56

8x7=4x2x7=4x7x2=(4x7)x2
To find 8x7, multiply 4x7 by 2.

Hope this helps :)

Find the equivalent expression by drawing a line from the left column to the right
Gala2k [10]

Answer/Step-by-step explanation:

2(3x - 1) = 2*3x 2*-1 = 6x - 2

(x*y)2 = (xy)2 = 2xy

2(2x - 3) = 2*2x 2*-3 = 4x - 6

3x + 4x + 2 = (3x + 4x) + 2 = 7x + 2

7x - 7 = 7(x) - 7(1) = 7(x - 1)

x(6 + 9) = x(15) = 15x

2 + 9x + 1 + 3x = (9x + 3x) + (2 + 1) = 12x + 3

4(x + 2) + x = 4x + 8 + x = 4x + x + 8 = 5x + 8
