I need help finding the area of these two
1 answer:
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A = × (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A = × (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²

Hi!
I can help you with joy!
The answer is 2x= 6x.
This is an example of direct variation!
D. 1/4 + 1/5 = 5/20 + 4/20 = 9/20 = 45/100 = 0.45
2(n+9)=6 divide both sides by 2
n+9=3 subtract 9 from both sides
n=-6
check
2(-6+9)=6
2(3)=6
6=6
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
