Answer:
4:5
Step-by-step explanation:
You are doing ratios
Answer:
2x + 3y = -6
-4x + 3y = 12
5x + 3y = }
x - y = 5
Step-by-step explanation:
Standard Form is
.
2x + 3y = -6, -4x +3y = 12, 5x + 3y = '?', and x - y = 5 are the equations that are in standard form.
'2x+3 = 6' does not have the 'y' to make it standard form.
'y = 2x + 5' is slope-intercept form.
Answer:
A = 1,307 cm^2
Step-by-step explanation:
Formula of Surface Area of a Rectangle:
A = 2 (lw + lh + wh)
length*width = (20)(23) = 460
length*height = (23)(4.5) = 103.5
width*height = (20)(4.5) = 90
A = 2 (460 + 103.5 + 90)
A = 2(653.5)
A = 1,307 cm^2
Answer:

Step-by-step explanation:
