You answer is C because 7-(-2) is 9 and then u just had an X at the end .
Hope this helps:)
Answer:
B & D
Step-by-step explanation:
both B and D are non linear because they're not lines
Answer:
The Pythagorean Theorem is used for right triangles only, because it's a mathematical relation between the legs of the triangle and the hypothenuse, where each leg must be less than the length of the hypothenuse.
It's important to correctly identify each element of the triangle, that is, which sides are legs, and which side is the hypothenuse, because the Pythagorean Theorem has a specific order, that means, if we make a mistake identifying each element, then the result will be wrong.
For example, the expression 
is the theorem, where 
is the hypothenuse. This theorem states that the square of the hypothenuse (longest side) is equal to the sum of the square of the legs. So, if we call a leg instead of the hypothenuse, the theorem won't work.
C-1=13 — Combine like terms.
13+1=14 — Cancel the one out.
c=14 — Answer.
A mixed <u>fraction</u> is an improper fraction turned into a whole number and a proper fraction
proper fraction: top number is SMALLER than the bottom number (fraction means part of) exg 1/3
improper fraction: top number is GREATER than the bottom number (more than 1) exg. 4/3
mixed: an improper fraction written as a whole number and a proper fraction exg
4/3=imporper mixed=1 and 1/3
so
575%
percent means parts out of 100
575%=575/100=57.5/10=5.75/1=5.75/1=5.75=5 and .75/1
we know that 0.75=3/4
so
5 and 3/4 is the answer
