Y equals 3x-3 is the answer
The correct answer is the 2nd one
Answer:
5a(6a-7) = 30a² - 35a
Explanation:
Before we begin, remember the following:
a(b+c) = ab + bc
Now for the given:
Assume that the first question mark is x and that the second question mark is y.
The expression now becomes:
(6a-x) * 5a = ya² - 35a
Distribute the 5a over the bracket and equate it with the right-hand side as follows:
5a(6a) - 5a(x) = ya² - 35a
30a² - 5ax = ya² - 35a
By comparison:
30a² = ya² ..............> This means that y = 30
-5ax = -35a
-5x = -35
5x = 35
x = 35/5
x = 7
Based on the above, the expression is:
5a * (6a-7) = 30a² - 35a
Hope this helps :)
36 there you go I hope you understand
