Answer: True

Step-by-step explanation:

The area of a trapezoid is ((b1+b2)/2)*h.

Because this trapezoid is an isosceles trapezoid, we can find the base of the right triangles: 4.  Then, using Pythagorean theorem we can get the height of the trapezoid, the square root of 33, or about 5.75.  Then plugging the values into the formula, we get 86.25, which is close to 86.2.

Hope it helps <3

PLEASE HELP It's for 10pts
Eduardwww [97]

Answer:

9x+2

Step-by-step explanation:

It's a simple problem, to find the perimeter, add a+b+c. In this case, it's with binomials, but it follows the same idea.

(2x+2)+(3x+1)+(4x-1)

2x+2+3x+1+4x-1

Combine like terms.

2x+3x+4x=9x

2+1-1=2

Left with 9x+2 as your perimeter binomial.

Please help... How many odd perfect squares are between 5 and 211?
frez [133]

Answer:

we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Step-by-step explanation:

Let us check by taking squares

  • 3² = 9
  • 5² = 25
  • 7² = 49
  • 9² = 81
  • 11² = 121
  • 13² = 169

As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.

Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

How would you find the volume of the solid in the figure ?
djverab [1.8K]
Finding Volume is dependent upon which object you are seeking.

Rectangle, Volume=length*width*height

Cube, Volume=S^3

Cylinder, Volume= \pi*r³*h

Sphere, Volume=4/3*\pi*r^3

Helpppppppp me plzzzzzzz

Answer:

Length of Line AC = 26 units

Step-by-step explanation:

Given:

Line AC = [3x + 1] + 8

Line BC = [x - 2] + 2

Find:

Length of Line AC

Computation:

Line AB ║ Line L

So,

Using Mid-Point theorem;

[3x + 1] / 8 = [x - 2] / 2

2[3x + 1] = 8[x - 2]

6x + 2 = 8x - 16

8x - 6x = 16 + 2

2x = 18

x = 9

So,

Line AC = [3x + 1] + 8

Line AC = [3(9) + 1] + 8

Line AC = [27 + 1] + 8

Line AC = 28 + 8

Length of Line AC = 26 units
