b = (a - 3)²
Our aim is to get <u><em>a</em></u> to be alone
1) First we get rid of what's in the brackets. So we subtracts each side by 3. Of course, the opposite of subtracting is adding:
b+3 = a²
2) Now we get rid of the squared in a. Opposite of squaring is square rooting.
3) There we have it. a is now by itself. We can test if we're right by substituting.
Lets make a=2
b=(a-3)²
b= (2-3)²
b= 1
NOW:
Subst. the given x and y values: 6(-1)^4 * (3)^3
6 * 27 = 162
Note that you MUST do the exponentiation first.
Also note that your post would be much clearer if you'd please use " ^ " to denote exponentiation: 6x^4 * y^3
It would be three lines and the shape would be a triangle
Answer:
i'm doing the same question but i think it is a right triangle but in a different position.
Step-by-step explanation:
The volume of the prism is calculated by multiplying the length, L, width,W, and depth or height, H.
V = L x W x H
Fish tank:
V = 50 cm x 25 cm x 25 cm
= 31250 cm³
Depth of the water in tank (with castle - without castle)
d = 57.5 cm - 48 cm = 9.5 cm
Volume of the caste:
V = 9.5 cm x 50 cm x 25 cm = 11875 cm³
