To find a perimeter, add all sides together:

9) 12 + 12 + 8 + 8 = 20 + 20 = 40 in
10)  3 + 3 + 3 + 3 = 6 + 6 = 12 cm

To find area, multiply length and width, or base and height:

11) 3 x 6 = 18 
12) 10 x 30 = 300 ft
13) 12 x 12 = 144 cm
14) 7 x 4 = 28 m

15) 
Perimeter: 2(2) + 2(16) = 4 + 32 = 36
Area: 1 x 16 = 16


hope this helps

Convert y=-1.4x+9.6 to standard form
pychu [463]

Answer:

14x-10y=-96

Step-by-step explanation:

we know that

The equation of the line in standard form is equal to

Ax+By=C

where

A is a positive integer

B and C are integers

so

we have

y=1.4x+9.6

Multiply by 10 both sides

10y=14x+96

isolate the variable x and y (Remember that A must be positive)

14x-10y=-96 -----> standard form

If 42 pushups is done in 3 minutes how many can be done in 5
tresset_1 [31]
So first find out how many can be done in 1 minute.
In an equation it would be 3x=42
Divide by 3
x=14
So 14 pushups can be done in 1 minute (congratulations to this person I can barely do one haha)
So now you multiply what you can do in 1 minute by 5 minutes.
14x5= 70 pushups
