The correct answer to your question is A.) Reflectional
First, you have to distribute the -1 throughout the parentheses, which gives you 7x-3x-10=-46.
Then, you combine 7x and -3x, which gives you 4x-10=-46.
Then, you add 10 to both sides of the equation, which gives you 4x=-36.
FInally, you divide both sides of the equation by 4, which gives you x=-9.
The answer is C=10
This is the Pythagorean theorem, it solves for the hypontunuse. Basically it tells you the missing sides length.
It’s really simple once you get the hang of it. The formula is
A^2+b^2=c^2
Plug in the side lengths you have (6 and 8)
6^2+8^2=c^2
36+64=c^2
100=c^2
DO NOT PUT 100 AS ANSWER
You then take the square root of 100, to get 10^2
W=7
L=19
Don’t mind the problem above. Hope this helps
