PLEASE HELP WITH FINDING AREA

Mathematics

When you have an irregular figure, you can divide it so that it becomes multiple normal figures. You already did this in the picture, now you just have to find the area of each shape and then add them all together.

From bottom to top:

A=1/2 (b1+b2)h

A= 1/2 (4+2.24)(2)

A= 6.24

(you have two of these on either side)

A=bh

A=6(4)

A=24

A=1/2 bh

A= 1/2 (4)(4)

A=8

(NOTE: there is an error in your drawing. The height of the triangle cant be determined because the 10 value spans over the entire figure when the wings of the rocket are 4 units long and then the body is 6 units long, making it equal 10 already. I'm assuming that the 10 is supposed to go from the bottom of the rectangle to the top of the triangle)

Total figure= 6.24 + 6.24 + 24 + 8

total figure = 44.48

There are 60 cars in a used car lot.
PilotLPTM [1.2K]

Answer:

Honda made 32 cars

Step-by-step explanation:

Total no. of cars = 60

car made by ford = 3/10 of total no of cars

car made by ford = 3/10 of 60 = 3/10* 60 = 18

car made by General Motors = 1/6of total no of cars

car made by General Motors = 1/6 of 60 = 1/6* 60 = 10

No of cars made by Honda = Total no. of cars - car made by ford - car made by General Motors

No of cars made by Honda = 60 - 18 - 10 = 32

In this lot, Honda made 32 cars.

Not sure how to do this problem
myrzilka [38]
First we need to write the factors of the polynomial. In order for 1, 4, and -3 to be roots, they need to be the x values that make the polynomial equal 0.

(x - 1) = 0

That would be the factor for x = 1 because when we plug 1 in for x we get 1 - 1 which equals 0.

Multiply all the factors together.

(x-1)(x-4)(x+3)=0

Now FOIL.

(x^2-5x+4)(x+3)

x^3-2x^2-11x+12
