Answer:
29
Step-by-step explanation:
Ok so with there being an X beside the number you go ahead and multiply the X and the number its beside (12) so 12x3=36 then you subtract 7 from 36 which will get you 29 hope this helped!
6.5 ÷ 1345 = 0.0048 or 13/2690
Answer:
12x + 7 is the answer
Step-by-step explanation:
We don't know whether those two sides are both legs
of the right triangle, or if BC is the hypotenuse.
If AC and BC are both legs, then
AB = √ (AC² + BC²)
= √ (7² + 8²)
= √ (49 + 64) = √ 113 .
If BC is the hypotenuse of the right triangle, then
AB = √ (BC² - AC²)
= √ (8² - 7²)
= √ (64 - 49) = √ 15 .
