So you would act like it was an equal sign and solve it like normal. Subtract 45 from both sides. Get 14"="2x. Divide by 2 and get 7 >x. If you were to multiply or divide by a negative than you would flip the sign, but you leave it in this case because you divided by a positive. I hope that helps.
Divide the top number by the bottom number, then move decimal point to the right two spots .
Use pythagorean theorem for all of them
a. 3, 4, 5
3^2+4^2?5^2
9+16?25
25=25
right
b. 5, 6, 7
5^2+6^2=7^2
25+36=49
61>49
acute
c. 64+81=144
145>144
acute
hope this helps!
Answer:
7
Step-by-step explanation:
P=68
P=2L+2(9)
-----------------
Therefore:
2L+2(9)=68
2L+18=68
2L=68-18
2L=50
L=50/2
L=25
---------------
So the length is equal to <u>25 inches</u>.
