10.

Get x by itself

x^2 = 16 (divide by 3 after moving 48 to other side)

Square root

x = 4, -4

11.

Once again get x by itself

x^2 = 4 (divide by 4 after moving 10 to the other side)

Square root

x = 2, -2

12. To find this we will model the equation like so

2W x W = 72

W is the width

2w is the length because it is twice the width

simply

w^2 = 36

square root

width is 6 and the length is 12

13.

To find the solutions we must factor the equation

(x+5)(x-2) satsify the equation

Then solve for x X + 5 = 0 and X - 2 = 0

x = -5, 2

Alfonso earned a score of 87.5% on his test. he did 56 problems correctly. how many problems were on the​ test?
Yuri [45]
64. 87.5% in fractions is 7/8. We divide 56 by 7/8, and get to 64.
56 ÷ 7/8= 56 x 8/7= 448/7, which is reduced into 64.

Find the area. Round to the nearest hundredth when necessary. Be sure you are showing all work to find each figure.
eimsori [14]

<u>Additional requirements in figure</u> :-

Mark point :-

  • A
  • B
  • C
  • D
  • E

Draw a straight line from E to AB .

And the point line joins mark it as "F" .

It will generate quadrilateral FBCD.

we get to know In quadrilateral left angle is 90°

How ?

{

proof :

As three angles are given 90° So third angle will also be 90°

Reason:

→ Sum of interior angles = 2 (no. of angles - 2 × 180°

→Sum of interior angles = (4-2 × 180°)

→Sum of interior angles = (2 × 180°)

→Sum of interior angles = 360°

}

<u>✿</u><u>Now let the left angle be </u><u>x</u>

  • 90° +90° + 90° + x = 360°
  • 180° + 90° + x = 360°
  • 270° + x = 360
  • x = 360° - 270°
  • x = 90°

<u>we know</u> :

Area of rectangle = Length × Breadth

STEPS :

  • Area of rectangle = Length × Breadth

  • Area of rectangle = 7 × 8

  • Area of rectangle = 56 in²

<u>Now let's find EF</u> :

  • EF = BD - EC

  • EF = 7 - 4

  • EF = 3 in

<u>To find A</u>

<u>F</u> :

  • A•F = AB - CD

  • A•F = 12 - 8

  • A•F = 4 in

<u>In triangle AFE</u>:

  • EF is base of triangle
  • A•F is height of triangle

We know :

<u>Area of triangle =(</u><u> </u><u>Height</u><u> </u><u>×</u><u> </u><u>Base)/2</u>

Steps :

  • Area of triangle = (Height × Base)/2
  • Area of triangle = (4 × 3)/2
  • Area of triangle = 12/2
  • Area of triangle = 6 in²

<u>To find area of figure</u> :

  • Area of figure = Area of rectangle + Area of triangle
  • Area of figure = 56 + 6
  • Area of figure = 62 in²
