Answer:
Option D is correct
Surface area of a cube is 294 square units
Step-by-step explanation:
Surface area of a cube is given by:
square unit
where
S is the surface area of a cube
a is the length of edge of a cube.
From the given figure, we have;
a = 7 units
then;
square units
Therefore, the Surface area of a cube is 294 square units
Answer:
x=33
Each base angle measures 69 degrees
Step-by-step explanation:
the 2 base angles are equal so the measure of 1 base angle = (180 - 42) / 2
= 69 degrees
2x + 3 = 69
2x = 66
x = 33
There are 99 of them.
The smallest one is 2 .
The largest one is 198.
Answer:
x = 6
Step-by-step explanation:
5x + 15 = 45
Subtract 15 from both sides
5x = 30
Divide by 5 on both sides
x = 6
Hope this helps :)
I think as that is a variable so when you like add there is already a constant so it is 1
1+1+1+1= 4
x=1
