2(-2.5)(-7.5) + 2(-2.5)^{2}
= 50
Standard form is the same as numerical form
e.g: thirty-five in standard form=35

Answer:
96 yards
Step-by-step explanation:
This is basically just a huge addition problem that we can tackle (heh) in our heads.
If we gain yards, then we add.
If we lose yards, then we subtract.
If we started out at 50, the expression is
.
We can use the associative property of addition to simplify this. I'm just grouping together things that look easy to do in my head.

Answer:
![\sqrt{149\\ \\](https://tex.z-dn.net/?f=%5Csqrt%7B149%5C%5C%20%5C%5C)
However, that's the length of "c" and you're looking to drag it in. So,o you drag in 10^2+7^2=a^2.
Then, as shown by the first picture attatched, you can drag in the one with "c" and "a" with the five shown.
Step-by-step explanation:
To find "c" the diagonal, as explained, you need to use the theorem twice. You can first use it by finding "a", as you already have "b". To find a, you do 10^2+7^2=a^2, the hypotenuse.
100+49=149.
So, a is root 149.
a^2+b^2=c^2 so
149+25=174
