Answer:
The first error occurs in Step 3
The value of the equation is -69
Step-by-step explanation:
The error is that 3-0+(-72) is actually supposed to be 3-0-72 because once you multiply the positive 36 and the negative 2, the equation automatically becomes negative.
Simplify the following:
7 - 3 (9×2 n + (3 n + 8 n)/(-n))
3 n + 8 n = 11 n:
7 - 3 (9×2 n + (11 n)/(-n))
(11 n)/(-n) = n/n×11/(-1) = 11/(-1):
7 - 3 (9 2 n + 11/(-1))
Multiply numerator and denominator of 11/(-1) by -1:
7 - 3 (9 2 n + -11)
9×2 = 18:
7 - 3 (18 n - 11)
-3 (18 n - 11) = 33 - 54 n:
33 - 54 n + 7
Add like terms. 7 + 33 = 40:
40 - 54 n
Factor 2 out of 40 - 54 n:
Answer: 2 (20 - 27 n)

Step-by-step explanation:
Formula for area of a triangle :
<u><em>Area (triangle) = 1/2 × base × height</em></u>
<u><em /></u>
=============================================================
Solving :
<u>Triangle 1 (Top Left)</u>
⇒ Area = 1/2 × 11 × 3
⇒ Area = 33/2
⇒ Area = 16.5 in²
<u>Triangle 2 (Top Right)</u>
⇒ Area = 1/2 × 8 × 7.2
⇒ Area = 4 × 7.2
⇒ Area = 28.8 cm²
<u>Triangle 3 (Bottom Left)</u>
⇒ Area = 1/2 × (5.5 + 5) × 10.4
⇒ Area = 10.5 × 10.4
⇒ Area = 109.2 m²
<u>Triangle 4 (Bottom Right)</u>
⇒ Area = 1/2 × (2 + 7) × 5.5
⇒ Area = 9 × 2.75
⇒ Area = 24.75 in²
