Answer:
X=6,-4
Step-by-step explanation:
0=x^2-2x-24
First substitute x with 6
0=(6)^2-2(6)-24
36-12-24
=0
Now try -4
0=(-4)^2-2(-4)-24
Two negative numbers time each other turns it into a positive number -4 x -4=16
24-24=0
Answer:
Option A: 1.50x +15
Option B: 3x
After 10 rides, the total cost of each option will be the same. This total cost is $30
Step-by-step explanation:
X represents how many rides you take. After 10 rides, the total cost of each option will be the same. To find that, keep plugging in numbers into x until the numbers are the same. This total cost where the numbers are the same is $30.
Answer: The artist used 8.6 inches more of silver wire
Step-by-step explanation:
Perimeter of the square
P = 4*a
P = 4*a = 40 in
a = 10 in
Each side of the square has a length of 10 in
The diameter of the circle is equal to the length of the side of the square
Diameter = 10 in
Perimeter of the circle
P_c = 2*π*radius = π*diameter
P_c = (3.14)*10 in = 31.4 in
Inches of silver wire (square) = 40 in
Inches of copper wire (circle) = 31.4 in
40- 31.4 in = 8.6 in
16) It would be: 6+5+3+2 - 1+3+6+4 = 16 - 14 = 2 in.
17) -8/2 + -6/1 + -9/3+ -6/2 = -4-6-3-3 = -16
