Answer:
+ 8b + 11 + 6x + 5c
Step-by-step explanation:
Split 8b + 11 + 6x + 5c
into two 2-term polynomials
+ 11 + 8b and + 6x + 5c
This partition did not result in a factorization. We'll try another one:
8b + 11 and + 6x + 5c
This partition did not result in a factorization. We'll try another one:
8b + 6x and + 11 + 5c
This partition did not result in a factorization. We'll try another one:
8b + 5c and + 6x + 11
This partition did not result in a factorization. We'll try another one:
+ 5c + 8b and + 6x + 11
This partition did not result in a factorization. We'll try another one:
+ 6x + 8b and + 11 + 5c
All three partitions failed. Tiger finds no factorization
ANSWER
x=11
EXPLANATION
We want to solve the equation:
Add -8 to both sides:
Square both sides of the equation to get:
Rewrite in the form ax² +bx+c=0
Factor to get,
This implies that,
Checking for extraneous solutions.
When x=6, the original equation becomes,
2+8= 6 is not true.
x=6 is an extraneous solution.
When x=11, the original equation becomes,
This is true, hence x=11 is the only solution.
Answer: Christina weighs 98 pounds.
Step-by-step explanation: The formula to solve this problem is x + 17 + x = 179, where x equals Sarah’s weight.
X + 17 + x = 179
First you need to combine the x values:
2x + 17 = 179
Next, subtract 17 from both sides:
2x = 162
Finally, divide both sides by 2:
X = 81
Sarah’s weight is 81 pounds and Christina weighs 17 pounds more, which is 98 pounds. You can double check your work by adding both of their weights (98 + 81) to make sure that your answer is correct.
