What is the measure of x?

Mathematics
1 answer:
UkoKoshka [18]3 years ago
7 0

Answer:

x=4

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+5) *x = 6^2

x^2 +5x = 36

Subtract 36 from each side

x^2 +5x - 36 = 0

Factor

( x-4) (x+9) = 0

Using the zero product property

x-4 = 0  x+9 =0

x = 4  x=-9

Cannot be negative since that is negative length

x=4

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)
tangare [24]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =-2\\y_{1} =4\\x_{2} =6\\x_{1} =-2

^^^Plug these numbers into the formula for slope...

\frac{-2 - 4}{6 - (-2)}

\frac{-6}{8}

^^^Can be further simplified to...

\frac{-3}{4}

^^^This is your slope

Hope this helped!

Answer:

1. a) 8 cm × 8 cm = 64 sq cm

b) (64 cm²) × 6 squares = 384 sq cm

2. 152 sq cm

Step-by-step explanation:

1. The area of any rectangle is the product of its length and width. For a square, length and width are the same. The square faces of your die have length and width of 8 cm, so the area is (8 cm) × (8 cm) = 64 sq cm.

A cube has 6 faces of identical size, so the total surface area is 6 times the area of one face. Your cube's surface area is 6 × 64 sq cm = 384 sq cm.

___

2. A rectangular prism (cuboid) has 6 faces—3 pairs that are the same size. The area is the total of the areas of these pairs of faces. It can be computed by ...

A = 2(LW + WH + LH)

For your rectangular prism, this is ...

A = 2((8 cm)×(6 cm) + (6 cm)×(2 cm) + (8 cm)×(2 cm))

= 2(48 sq cm + 12 sq cm + 16 sq cm)

= 2×(76 sq cm)

= 152 sq cm
