1:1 is a square ratio rather than horizontally long rectangle, which would be similar to 720x1080
Answer= $138.98
47.86-25.20+52.75-22.04-8.50+94.11=$138.98
Answer:
Y=(-1/2)x+9/2
Step-by-step explanation:
For straight lines y=mx+c
m=gradient
Find the gradient first-m=(y2-y1) /(x2-x1)
Take the points M and N and substitute in the equation
m=(5-2)/(-1-5)
m=-1/2
Gradient of line MN×gradient of perp line =-1
There fore gradient of perp line =2
The rectangular prism has measures 6 units by 6 units by x units,
Thus, the volume is 6*6*x = 36x (units cubed)
The surface area of the prism is
2(x*6+x*6+6*6)=2(6x+6x+36)=2(12x+36)=24x +72 (units squared.
36x=24x +72
36x-24x=72
12x=72
x=72/12=6
Answer: x=6
Answer: 4 and 8
Step-by-step explanation:
1. 12+7x=40
7x=28
x=4
2. 6x-3=45
6x=48
x=8
