The answer to that problem is 9600cm. each side of surface area will be the same multiplied together
Since the triangle is equilateral, QR = RS = QS.
a. MS = (1/2)74
MS = 37
b. Half of the equilateral triangle makes a right triangle. Use Pythagorean Theorem to find QM.
a^2 + b^2 = c^2
37^2 + b^2 = 74^2
1369 + b^2 = 5476
subtract 1369 from both sides
b^2 = 4107
take the square root if both sides
b = 64.1
QM = 64.1
<span>Its: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 </span>
First you will subtract right to left and then what ur left with is the sum.
The quadratic formula is 
.
From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:
Because there is a square root of a negative number, there is no solution.
