Answer:
A=4, B=3, C=2, D=7 or A=2, B=7, C=4, D=3
Step-by-step explanation:
To factor this, you are looking for factors of 8×21 = 168 that have a sum of 34.
168 = 1×168 = 2×84 = 3×56 = 4×42 = 6×28 = 7×24 = 8×21 = 12×14
The sums of these factor pairs are 169, 86, 59, 46, 34, 31, 29, 26. The factor pair whose sum is 34 is 6×28. This means we can rewrite the expression as ...
8x² +28x +6x +21
Factoring by pairs gives ...
4x(2x +7) +3(2x +7)
(4x +3)(2x +7) ⇒ A=4, B=3, C=2, D=7 or A=2, B=7, C=4, D=3
Answer:
The answer is: 7
Step-by-step explanation:
\frac{\frac{21}{4}}{\frac{3}{4}} = 7

We can solve this using proportion!
Answer:
there could be multiple ways to get to a certain number like 1 to 3 could be + 2 or multiplying 3 so you have to check the next numbers to see if it is adding 2 or multiplying 3
