7^2+8^2=113
the answer is sqrt(113)
Answer:
Step-by-step explanation:
<u>Given</u>
- Q = 7m + 3n,
- R = 11 - 2m,
- S = n + 5,
- T = -m - 3n + 8
<u>Simplify [Q - R] + [S - T]</u>
- (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
- 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
- m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
- 10m + 7n - 14
Answer:
A number plus two and three-tenths. → x + 2.3
A number divided by three-tenths. → x / .3
Four, subtracted from three times a number. → 3x - 4
Four, added to twice a number. → 2x + 4
Hope that helps.
Answer: 12
Step-by-step explanation:
<em>Although you have not included which value is the hypotenuse or if they are legs, I will assume the hypotenuse is 20, due to the triangle appearing to be a multiple of the standard 3-4-5 triangle.</em>
The pythagorean theorem is a^2+b^2=c^2, where a and b are the legs and c is the hypotenuse. Thus, plug in the values to get:
