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

Answer:
Step-by-step explanation:
2n - 6
a) n = 1 ; 2n - 6 = 2*1 - 6 = 2 - 6 = -4
n = 2 ; 2n - 6 = 2*2 - 6 = 4 - 6 = -2
n = 3 ; 2n - 6 = 2*3 - 6 = 6 - 6 = 0
b) n=10; 2n - 6 = 2*10 - 6 = 20 - 6 = 14
Answer:
.55
Step-by-step explanation:
You want to shorten the decimal to just to two after the decimal point. If so for example, .443 would be shortened to .44, but if the third number is 5 and up, you would take the second number after the decimal point and add 1. For example,
.446 would round up to .44, which is why .5524 would round to .55
