AB = 18   BC=8   CD=5

Let's call E that point at the other end of x, so x=DE.

Secant Secant theorem says

CE × CD = AC × BC

and since CE = CD + DE,   AC = AB + BC

(CD + DE) CD = (AB + BC) BC

Substituting,

(5  + x)(5) = (18 + 8) (8)

5  + x =  (26)(8)/5

x = -5 +  (26)(8)/5 = 183/5 = 36.6

Answer: 36.6, last choice

T.L. and Quina plan to add a 6-inch thick layer of gravel to their driveway. The driveway is 15 yards long and 3 yards wide. Wha
Artemon [7]

Answer:

Step-by-step explanation:

The driveway has the shape of a cuboid. The formula for determining the volume if a cuboid is expressed as

Volume = L × W × H

Where

H represents the thickness of the gravel to be added to the driveway.

W represents the width of the driveway.

L represents the length of the driveway.

From the information given,

L = 15 yards

W = 3 yards

H = 6 inches.

36 inches = 1 yard

6 inches = 6/36 = 0.167 yard

Therefore, the volume of gravel required would be

V = 15 × 3 × 0.167 = 7.515 cubic yards

2.Solve the system using substitution.
Lena [83]
2x+2y=38
y=x+3

First you would substitute the y for x+3
2x+2(x+3)=38

You would multiply the 2 by the x+3
2x+2x+6=38

Add the 2x and the 2x
4x+6=38

Subtract the 6 on both sides
4x=32

Divide the 4 on both sides
x=8

Now substitute the x in the second problum for 8
y=8+3

Add the 8 and the 3 to solve for y
y=11

Your answers
x=8
y=11
the correct answer would be A:(8,11)
