Answer:
the first and last one
Step-by-step explanation:
3*3*3/3*3*3*3*3
3^3
What do you need to calculate? The area?
If so you can devide this into 2 piseces the upper part and the lower one.
The first one is 16*6
And the other one is 10*6
Making this an area of 96+60=156m^2
Answer:
Step-by-step explanation:
(14 * 10)+ (14 * 7) = 14 * (10 + 7) = 14*17 = 238
To do this, add the equations together like this,
3x + 4y = 2 plus
4x - 4y = 12
-x = 14
Multiply the negative sign to both sides because the x cannot be a negative.
x = -14
Now plug in -14 for a x value in one equation, like this to get the y value:
3(-14) + 4y = 2
-42 + 4y = 2
Add 42
4y = 44
y = 11
Your x and y values are:
x = -14
y = 11
