Answer:
2R^2 + 21R - 36
Explanation:
To answer this question, we will follow these steps:
1- expand the brackets
2- gather like terms
Steps are as follows:
(2R-3)(R+12) = 2R(R) + 2R(12) - 3(R) - 3(12)
= 2R^2 + 24R - 3R - 36
= 2R^2 + 21R - 36
Hope this helps :)
<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J
</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8
D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z
The expression that more usefull would be D=4z+8 if you want to determine David age.
2. The total number of ornaments in the boxes is 95. Multiply 19 and 5 to get the answer.
3. First, convert the inches to feet. 1 inch is equal to 0.083 ft. Thus, 39 in = 3.25 ft and 75 in = 6.25 ft. Calculate the area of one bed using formula for rectangles. Multiply length and width of the first bed. Length is the longer side of the bed while width is the shorter side.
A = 6.25 ft x 3.25 ft
<span>A = 20.31 ft</span><span>
Multiply this by 2 since Carrie needs fabric to cover twin beds. The answer is 40.62 ft.
