Three more than 8 times a number is 29. Find the number.
yanalaym [24]
Well, first off, to solve for this, we can write the expression and then solve from there.
Expression: 8x + 3 = 29
So, now that we have our expression, we can solve for our missing number using the balancing method.
8x + 3 = 29
8x + 3 - 3 = 29 - 3 (we subtracted the three because we needed to get rid of the three on the left side of the equation do now we are just left with 8x = 26.
8x = 26
8x/8 = 26/8. (So, the 8 on the left side cancels out and we are just left with X.
X = 26/8
X = 13/4
X = 3 and 1/4
So, in conclusion, the answer to this question is: X = 3 and 1/4 as a mixed number or 13/4 as an improper fraction.
Glad I could help!

Help plsss thank youuuu
MArishka [77]

<u>Answer:</u>

A. (x+5)

<u>Step-by-step explanation:</u>

We are given a quadratic expression x^2+8x+15 which we will factorize to see which of the given options is a binomial factor of it.

x^2+8x+15

Finding the factors of 15 such that when added, they give a result of 8.

x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)

Therefore, we can see that (x+5) is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
