4 x 8 x 6 x 4 x 26 = 19,968
i think however, i could be wrong. my teacher told me to use the fundamental counting principle. you multiply each different part of the problem.
Step-by-step explanation:
total surface area of a cube = side × 6
25=side since all the sides of a cube are equal
25×6=
150cm
-4m +18-6=0
-4m+12=0
-4m=-12
m=3
Answer:
Step-by-step explanation:
The last one is spherical
The volume of a sphere is given by:
From the diagram, the the radius is r=6.2 cm.
We substitute to get:
This evaluate to;
The correct question is:
Using the digits 1 to 9 at most one time each place a digit in each box to create an equation where x is a negative value solve your equation to prove your answer.
__x + __ = __
Answer:
1. 9x + 8 = 1
2. 7x + 6 = 2
3. 5x + 4 = 3
Step-by-step explanation:
1. 9x + 8 = 1
Subtract 8 from both sides
9x = 1 - 8
9x = -7
Divide both sides by 9
x = -7/9
2. 7x + 6 = 2
Subtract 6 from both sides
7x = 2 - 6
7x = -4
Divide both sides by 7
x = -4/7
3. 5x + 4 = 3
Subtract 4 from both sides
5x = 3 - 4
5x = -1
Divide both sides by 5
x = -1/5
