Answering pretty sure yes
Step-by-step explanation:
Answer:
A = 70 units²
Step-by-step explanation:
Since all 4 sides are congruent then figure is a rhombus
The area (A) of a rhombus is calculated as
A = × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then
A = × 14 × 10 = 7 × 10 = 70 units²
Answer:
8/125cm3
Step-by-step explanation:
A=lxwxh
A=2/5 x 2/5 x 2/5
A=8/125cm
I hope this helps <3
9(8 - x) = 3x Distribute/multiply 9 into (8 - x)
72 - 9x = 3x Add 9x on both sides
72 = 12x Divide 12 on both sides
6 = x
Your answer is A
[proof]
9(8 - x) = 3x
9(8 - 6) = 3(6)
9(2) = 18
18 = 18
