Answer: x = 6
Step-by-step explanation:
Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.
Next, we set up the proportion as follows:

Then, you cross multiply to get the equation:

After solving down algebraically, you get the value of x to be 6.

What's the question? equals?
Step-by-step explanation:
8qх + 21ру + брx + 28qy
8qх + 28qy + брx + 21ру rearranged the terms to help factoring
4q(2x + 7y) + 3p(2x + 7y)
(2x + 7y)(4q + 3p) or (4q + 3p)(2x + 7y)
Answer:
0
3
10
21
36
Explination:
0 x anything is still zero, but I don't know if that counts.
1 (2+1) = 3
2 (4+1) = 10
3 (6+1) = 21
4 (8+1) = 36
