Answer:
22.4 cm^2
Step-by-step explanation:
Area of a parallelogram= base x height
or bxh
here base is 8cm and height is 2.8cm so,
Area = 8x2.8
= 22.4 cm^ 2
All we have to do is get y alone and input our values to see if it makes the statement true.
y - 1 = 3(x + 2)
Add 1 to both sides.
y = 3x + 7
y = 3(1) + 7
y = 3 + 7
y = 10
FALSE
y - 2 = 3(x + 1)
Add 2 to both sides.
y = 3x + 3
y = 3(1) + 3
y = 3 + 3
y = 6
FALSE
y + 1 = 3(x - 2)
Subtract 1 from both sides.
y = 3x - 7
y = 3(1) - 7
y = 3 - 7
y = -4
FALSE
y + 2 = 3(x - 1)
Subtract 2 from both sides.
y = 3x -5
y = 3(1) - 5
y = 3 - 5
y = -2
TRUE
The only equation that makes this statement true is D, y + 2 = 3(x - 1).
Answer:
V =836 cm^3
Step-by-step explanation:
The volume is V = Bh where B is the area of the base times the height
V = 38 * 22
V =836 cm^3
1st and 2nd shows = 2,580 + 2,920 = 5,500
If average = 3000 so 3 shows must be 3 x 3000 = 9000
So 3rd show = 9,000 - 5,500 = 3,500
Answer
3,500
