Almost. Where you put -(-5) and then later on you say it’s -5. It’s not. It would be +5 or just 5 because - and - makes a plus :)
Answer:
t = 4
Step-by-step explanation:
13 + t = 17
t = 4
13 + 4 = 17
An easier way to solve a question like this is to subtract the number given by the answer.
Example:
17 - 13 = 4
ANSWER
The radius is 4
EXPLANATION
The given equation is:
We complete the square to get the expression in standard form:
We factor using perfect squares to get:
This implies that,
Comparing to
The radius is r=4
Answer:
x = 5
x = 0
Pulling out like terms :
2.1 Pull out like factors :
x2 - 5x = x • (x - 5)
Equation at the end of step 2 :
x • (x - 5) = 0
Step 3 :
Theory - Roots of a product :
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
