Answer:
(x - 6)(x + 3)
Step-by-step explanation:
Given
x² - 6x + 3x - 18 ( factor the first/second and third/fourth terms )
= x(x - 6) + 3(x - 6) ← factor out (x - 6) from each term
= (x - 6)(x + 3)
For the scale factor, use the dimensions from similar sides:
Using 18 from the original image you would use 6 from the scaled image.
18 /6 = 3
This means the scaled image is 3 times smaller than the original. Because the scaled image is smaller divide 1 by the scale factor to get 1/3.
Q2:
The scale factor is 1 inch = 12 miles.
Multiply the total inches by 12:
6.5 x 12 = 78 miles.
Answer:
B) 2771 cubic centimeter
Step-by-step explanation:
first find the volume of the cylinder
V=πr^2h
V=3.14*7^2*26
V=4002.39
then find the volume of the cone
V=πr^2h
/3
V=3.14*7^2*24/3
V=1231.5
subtract the volume of the cone from the cylinder
4002.39-1231.5
2770.89
round to the nearest whole number
2771
4x^2 + x + 3 = 0
x = [-1 +/- sqrt (1^2 - 4 * 4 * 3)] / 8 = - 1 +/- sqrt ( --47) / 8
= ( - 1 +/- sqrt47i) / 8 = -0.125 + 0.857i , -0.125 - 0.857i
Answer:
35
Step-by-step explanation:
700 / 100 = 7
7 = 1%
7 x 5 = 35
35 = 5%
