4b. Laura has a 12-foot ladder. The safety instructions recommend the
base of the ladder be placed 4 feet from the base of the wall. How highwill the ladder be able to reach on the wall? WRITE YOUR ANSWER AS A SIMPLIFIED RADICAL. (HINT: Use the abbreviation sqrt to mean "square root of." For example an answer might look like 5sqrt3, and be read "five times the square root of 3".)
The answer is fourteen, I think. Because 14*14=196.
If you’re trying to find y the answer should be anything that equals more than negative 7 for example y could be 10
2x+(x-10)=4
3x-10=4
3x=14
x=4.6 repeating
