Answer:
She spent 8 dollars.
Step-by-step explanation:
24 divided by 3 is 8
When there is only one variable, the degree is the highest exponent.
Degrees of each term from L to R: 7, 4, 3, 11, 6, 7
The biggest of these is 11.
Final answer: 11
C
You can use the pythagorean theorem.
5^2+4^2 =c^2 (or length of AB in this case)
25+16=c^2
41=c^2
c (or length of AB) = sqrt 40
1) A square has 4 congruent sides, and the perimeter is the sum of these 4 sides. So perimeter = 3x+3x+3x+3x, which can also be expressed by 4(3x), simplified, it equals to 12x.
2) x^2 + 6x + 8
3) x^2 - 4x - 12
