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:
One solution, x=-18/11.
Step-by-step explanation:
y=1/2x-7
y=6x+2
---------------
1/2x-7=6x+2
1/2x-7-6x=2
1/2x-6x=2+7
1/2x-12/2x=9
-11/2x=9
x=9/(-11/2)
x=(9/1)(-2/11)
x=-18/11
Answer:
eleven below zero
Step-by-step explanation:
the opposite of -11 would be 11 not -11 so that one is out
positive elven is just 11 not -11 so that one is out
eleven greater than zero would just be 11 not -11
and eleven below zero would be -11 so thats the answer
