Answer:
10x-40
Step-by-step explanation:
5 times 2x minus 40 works because of the distributive property
Keep your mom, you only have one. But anyway;
Use the Pythagorean Theorem: A^2 + B^2 = C^2
12^2 + 21^2 = C^2
144 + 441 = C^2
585 = C^2
square root of 585 = approximately 24.2
2 1/3 = 7/3
Both numbers should be improper fractions.
11/3 + 7/3 = 18/3
Now the fractions must be simplified
18 ÷ 3 = 6
So 11/3 + 2 1/3 = 6
