the answer is 4 because 16 and 20 can both be divided by 4.
Answer:
Step-by-step explanation:
There are several approach to solving a quadratic equation; factorization, completing the square, the use of 'the almighty formula etc. Though i didn't see the steps you followed in solving, but from your answer, it is obvious you made good attempt but something is missing, your answer should be (5+√57)/2 or (5-√57)/2
I forgot how to do this sorry
-3x+4=-17
subtract -4 from both sides
divide -3 from both sides
the answer is 7
<u>Given</u>:
Given that the parallelogram with the lengths 5x, 3x + 1, 2y - 5 and y.
We need to determine the values of x and y.
<u>Values of x and y:</u>
We know the property that the opposite sides of a parallelogram are congruent.
Thus, we have;
------- (1)
------- (2)
The value of x and y can be determined using the substitution method.
Substituting equation (2) in equation (1), we have;





Thus, the value of x is 3.
Substituting x = 3 in equation (2), we have;



Thus, the value of y is 10.
