Question 13 of 31 The equation (x^3 + 2x^2)(3x^2 +2x + 1) = x^3 (3x^2+2x+1)+2x^2 (3x^2 + 2x + 1) is an
example of which method/property?
A. Vertical multiplication
B. Collect like terms
C. FOIL
O D. Distributive Property

b) well because you get well

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
