Because it is an isosceles triangle, the two longer sides are the same length. Therefore multiply 6.3 times 2.
To find the length of the base subtract 12.6 from 15.7 to get 3.1 cm.
4b - 7 + 2b + 11 and b + 3 + b + 1 are congruent.
You add the common factors in each problem: 2b + 4 = 2b + 4
The answer is B. Have a nice day
24 = -v/3 (first you multiply 3 to each side)
<u>×3 ×3</u>
<u />72 = -v (then you divide -1 from each side)
-72 = v<u><u /></u><u />
