Answer:
Step-by-step explanation:
Since it is a right-angled triangle, we will apply Pythagoras Theorem.
<u>Given are:</u>
Base = 16
Perpendicular = x
Hypotenuse = 18
<u>Pythagoras Theorem:</u>
(18)² = (16)² + (x)²
324 = 256 + x²
Subtract 256 to both sides
324 - 256 = x²
68 = x²
Take sqrt on both sides
8.2 = x
x = 8.2
-12 n - 24 = -12 (n+2)
-12 (n+2) is the answer
Answer:
D. -12s squared + 11st - 2t squared
Step-by-step explanation:
FOIL:
-3s(4s) - 3s(-t) + 2t(4s) + 2t(-t)
- 12s² + 3st + 8st - 2t²
Simplify.
- 12s² + 11st - 2t²
1. 34/15
2. 11/6
3. 13/10
4. 35/12
5. 10/27
