5 0

Answer:

Area = 2m^8 - 6m^4 + 4.5

Step-by-step explanation:

Given

Base = 2m^4 - 3

Height = 2m^4 - 3

Required

The area

This is calculated as:

Area = 0.5 * Base * Height

Area = 0.5 * (2m^4 - 3) * (2m^4 - 3)

Open brackst

Area = 0.5 * (4m^8 - 6m^4 - 6m^4 + 9)

Area = 0.5 * (4m^8 - 12m^4 + 9)

Open bracket

Area = 2m^8 - 6m^4 + 4.5

What does x+x+x+x+x-1+1+1+1= ?<br><br> (Giving this for 30 points)
77julia77 [94]

First, let's add all the x's.

x + x + x + x + x = 5x

5x - 1 + 1 + 1 + 1

Now, let's add together all the 1's that are being added (not the 1 that is being subtracted from 5x).


1 + 1 + 1 = 3

5x - 1 + 3

3 - 1 = 2

5x + 2

There's no way you can actually solve this unless you know the value of x; without x's value, this is as simplified as the expression is going to get.


Hope this helps!

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approx
Angelina_Jolie [31]

Answer:

168.168 square inches

Step-by-step explanation:

Given data

From the question, we can deduce that the side of the square is 28in

Hence the area of the square is

Area= 28^2

Area= 784 square inches

Also, the diameter of the circle is 28 in

The radius = 14 in

Area of circle= πr^2

Area= 3.142*14^2

Area= 3.142* 196

Area= 615.832 square inches

Therefore the area of the shaded region is

= Area of Square - Area of Circle

= 784-615.832

=168.168 square inches

(I WILL MATK BRAINLIEST)Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
Jobisdone [24]

Answer:

  • 10m + 7n - 14

Step-by-step explanation:

<u>Given</u>

  • Q = 7m + 3n,
  • R = 11 - 2m,
  • S = n + 5,
  • T = -m - 3n + 8

<u>Simplify [Q - R] + [S - T]</u>

  • (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
  • 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
  • m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
  • 10m + 7n - 14
