Answer:
-3+8n
Step-by-step explanation:
7+8n-10
7 and 10 are both constants, so you'd add them together. However, since 10 is negative, it become 7+(-10), which is also just 7-10. 7-10=-3. Since 8n is the only number with a variable, it cannot be combined. Therefore, the expression becomes -3+8n.

2 answers: choice B, choice F
Explanation:
The discriminant is
D = b^2 - 4ac
D = (-5)^2 - 4(3)(-1)
D = 25 + 12
D = 37
This means 37 is under the square root, and we know the answers are B and F due to this. Also note with these two answer choices, they are in the form where...
- a = 3, so 2a = 2*3 = 6
- b = -5, so -b = -(-5) = 5
Choices A, C, D, and E can be eliminated as the discriminant for these is D = 13.

Big figure = 20 ft
Small figure = 7 ft
Take note: In finding the scale factor, we must make sure that the measurements of both figures are the same sides or line.
20 feet / 7 feet = 2.86 scale factor.
This means that the big figure is 2.86 times bigger than the small figure.
If the arrow had been pointed from the small figure to the big figure.
7 feet / 20 feet = 0.35 scale factor.
This means that the small figure is only 0.35 of the big figure.
Both are scale factors but in different perspectives.
