Ng the zero product property
warm-up
which are solutions of the equation (x + 5)(x-3) = 0?

For this case we have a factorized quadratic equation. We equal each factor to zero and thus find the roots:

Subtracting 5 from both sides we have:

Thus, the first solution of the equation is:

On the other hand we have:

Adding 3 to both sides:

Thus, the second solution of the equation is:

The solutions of the equation are:

the answer is 4.8 units on e2020.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
