Hello,
Here is the answer :
2x^3 + 8x .
Answer:
the X represents the width, since to get the area, you have to multiply length times width
Hope that helps!
The answer to your question is 1.6
Answer:
We have a small circle, that is dilated by a factor of 5/3 creating a larger circle.
If the smaller circle has a diameter D, then after the dilation, the larger circle will have a diameter equal to: (5/3)*D
We know that the area of the larger circle is:
A = 100*pi cm^2.
And the area of a circle of diameter d, is:
a = pi*(d/2)^2
knowing that the diameter of the large circle is (5/3)*D, we can find the value of D.
A = pi*( (5/3)*D/2)^2 = 100*pi cm^2
let's solve this for D:
pi*( (5/3)*D/2)^2 = 100*pi cm^2
( (5/3)*D/2)^2 = 100 cm^2
( (5/3)*D/2) = √(100 cm^2) = 10cm
D/2 = (3/5)*10cm
D = 2*(3/5)*10cm = 12cm.
Then the area of the smaller circle will be:
a = pi*(D/2)^2 = pi*(12cm/2)^2 = pi*(6cm)^2 = pi*36 cm^2
and pi = 3.14
a = pi*36 cm^2 = 3.14*36cm^2 = 113.04 cm^2

Answer:
- yes
- 5 × (6 - 3) = (5 × 6) - (5 × 3)
Step-by-step explanation:
The distributive property tells you the factor outside parentheses multiplies each of the terms inside parentheses.
The difference 6 -3 inside parentheses has two terms, and there is a factor of 5 outside those parentheses. The setup for the distributive property is there, so the distributive property can be used.
__
The outside factor multiplies each inside term. The sign can be left with the inside term, or can be placed between the products.
5 × (6 - 3) = (5×6) - (5×3)
__
or
5 × (6 - 3) = (5×6) +(5×(-3))
