Answer:

34.5 square meters

Step-by-step explanation:

We assume you want to find the area of the shaded region. (The actual question is not visible here.)

The area of the triangle (including the rectangle) is given by the formula ...

A = 1/2bh

The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...

A = (1/2)(11 m)(9 m) = 49.5 m^2

The rectangle area is the product of its length and width:

A = LW

The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...

A = (5 m)(3 m) = 15 m^2

The shaded area is the difference between the triangle area and the rectangle area:

shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2

The shaded region has an area of 34.5 square meters.

What is 14 - 10 + 5 + 3 + 2

andre [41]

Hey There!

To solve this problem you need to know the math term "PEMDAS". For this problem we will be using the A and S part (addition & subtraction). When an order of operation problem has only addition and subtraction, you solve the problem by the order of left to right. First, you do 14-10 which equals 4, then you add 5, which equals 9, then you add 9 to 3, that equals 12 then you add 2 to that which equals 14. You're final answer should be 14.

Hope This Helped ;)

If the area of the rectangle is given by the polynomial 2x^2-7x-15, what is the dimension of the reactangle in terms of x?

Irina18 [472]

Answer:

x - 5 and 2x + 3

Step-by-step explanation:

<h3>Given</h3>

Area of rectangle = 2x^2 - 7x - 15

Dimensions of rectangle

<h3>Solution</h3>

<u>Since the area is the product of the sides, let's try to factorize the given:</u>

2x^2 - 7x - 15=
2x^2 - 10x + 3x - 15 =
2x(x - 5) + 3(x - 5) =
(x - 5)(2x + 3)

<u>So the dimensions are:</u>

x - 5 and 2x + 3

How do you solve -9( -4r + 6s ) + 3s - 7(6s - 2r)

slavikrds [6]

Answer: 2.1 Pull out like factors :

6s - 2r = -2 • (r - 3s)

Equation at the end of step

((0-(9•(6s-4r)))+3s)--14•(r-3s)

Pulling out like terms

4.1 Pull out like factors : 6s - 4r = -2 • (2r - 3s)

Equation at the end of step

((0--18•(2r-3s))+3s)--14•(r-3s)

Final result :

Answer:

I want to answer 15%

Step-by-step explanation:

As for how to solve it I don't really know I would use process of elimination because the answer can't be so high that it's 45% so that's out. Personally I think that 35% is pretty high to so my best educated guess would be between 25% and 15% . Sorry this isn't more helpful.
