Answer:
He knows that 30÷5 is 6. He then multiplies 6 by 6 to get 36
Step-by-step explanation:
A is option is the best approach for him to find the answer.
Lateral edge because if its slant you would slide of
Given that the radius r of a circle is written as a function of the area A with the following equation:
![r=\sqrt[]{\frac{A}{\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%7D%7D)
The domain of the above function is the area A of the circle.
This is because, in this context, the area is an independent and unique variable.
A is the input value.
Answer:
189sq.cm
Step-by-step explanation:
Area of a parallelogram = b×h
= 21× 9
= 189 cm^2
1) Equal the two together (not including the ‘y’)
-x -2 = 4x + 3
2) put x together and the whole number together
* when switching sides, signs ( + & -) changes, watch out for that *
-x - 4x = 3 + 2
-5x = 5 divide by the # with x so you have x
—— ——-
-5. -5
x = -1
therefore, x = -1
For y just plug x into either equation
I’ll use y = 4x + 3
y = 4(-1) + 3
y = -4 + 3
y = -1
therefore, y = -1
