Answer: x = 6
Formula: ![(x+5)=11](https://tex.z-dn.net/?f=%28x%2B5%29%3D11)
Step-by-step explanation:
We know that an area of a triangle is half of a rectangle.
The bottom side must equal 11, since if the figure was a rectangle, the area would be multiplied by 2, giving us 44.
What minus 5 equals 11?
6.
So x must equal 6.
Multiply by 4
so next number will be 320
5x4 = 20
20x4 =80
80x4=320
Answer:
8
Step-by-step explanation:
Calculate the distance d using the distance formula
d = ![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
with (x₁, y₁ ) = z₁(6, 2) and (x₂, y₂ ) = z₂(6, 10)
d = ![\sqrt{(6-6)^2+(10-2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%286-6%29%5E2%2B%2810-2%29%5E2%7D)
= ![\sqrt{0^2+8^2}](https://tex.z-dn.net/?f=%5Csqrt%7B0%5E2%2B8%5E2%7D)

= 8
Answer:
-13
Step-by-step explanation:
(7−15−3+5−7)⋅1
Subtract 15 from 7 to get −8.
(−8−3+5−7)×1
Subtract 3 from −8 to get −11.
(−11+5−7)×1
Add −11 and 5 to get −6.
(−6−7)×1
Subtract 7 from −6 to get −13.
−13
