You could solve this by finding the area of the WHOLE figure and subtracting the piece that is taken out.
The area of the WHOLE rectangle is 18 * 15 = 270.
The area of the piece taken out is 9 * 10 = 90.
270 - 90 = 180 in^2

Let's separate this shape into three parts. A smaller rectangle at the top, and one at the bottom, and a bigger rectangle in the middle.

The smaller rectangle at the top:

The equation to find the area of a rectangle is
(a = area, l = lenght, w = width)

a = l · w
Put in the values
a = 18 · 3
a = 54

Since the smaller rectangle at the bottom has the same length and width, it has the same area. 

The bigger rectangle in the middle:

a = l · w
Put in the values
a = 8 · 9
a = 72

Now add all of the areas together to get the answer!

72 + 54 + 54 = 180

The answer is 180 :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

What is the sum of the polynomials? 11x^2-5 + x+4
liraira [26]

Answer:

11x^{2}+x-1

Step-by-step explanation:

we have

(11x^{2} -5) +(x+4)

we know that

The sum of a quadratic equation and a linear equation will be a quadratic equation

so

Combine like terms

(11x^{2})+(x)+(-5+4)

11x^{2}+x-1

The density of glass is 2.6 g/cm3 and the density of lead is 11.3 g/cm3. Does this mean there are more particles of lead in 1 cm
Colt1911 [192]
The answer is that there are more particles in 1 cubic cm. this is because within 1 cubic cm lead has 11.3g in compared to the 2.6 glass has. m/v= density. divide the masses over the volume and that will prove your answer.

Aldo takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $98 per credit
stealth61 [152]

Let Y = total cost of both schools.

The total cost would be ( number of credits at Westside x 98) + (number of credits at Pinewood x 115).

The total number of credits he is taking is 14.

If w is the number of credits at Westside, then for Westside you have 98w ( $98 times the number of credit hours)

The equation is now y = 98w +  (number of credits at Pinewood x 115).

The number of credit hours at Pinewood would be the total credit  hours 14 minus the credit hours at Westside w, so you have 14-w, which needs to be multiplied by the cost at Pinewood.

The equation is now y = 98w + 115(14-w)

This can be simplified using the distributive property to:

Y = 98w + 1610 - 115w

Y = -17w + 1610
