Answer:
36 units²
Step-by-step explanation:
rectangle with area of 12 square units is dilated by a scale factor of 3. What is the area?
Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
we use the inverse formula
12 * 3 =<em> </em>
<em>36 units²</em>
<em>-----------------------</em>
check
36 : 12 = 3
the answer is good

Answer:
2,714in^3
Step-by-step explanation:
V = pi*r^2*h
V = 3.14*6^2*24
V = 3.14*36*24
V = 2,714
The volume of the cylindrical fish tank is 2,714 inches cubed.
Answer:
Step-by-step explanation
Step 1: multiply the coefficient a and the constant c. Given that the general expression of a parabolic equation is ax^2+bx+c
3*5=15
Step 2: examine the coefficient b and try to find 2 numbers which you can multiply to get 15, add or subtract and get - 8
In this Case: - 3*-5=15 and - 3+(-5)= - 8
Step3:
You separate the equation in terms of the two factors you have found
3x^2-3x-5x+5=0
Step 4:Factorise
3x(x-1)-5(x-1)=0
(3x-5)(x-1)=0
