Answer:

4c² + 11cd + 5d

Step-by-step explanation:

To add monomials, you have to look at the variables that are accompanied by their coefficients. In the given problem, (–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd), you can combine both cd ut nt cd and c² and cd and d and d and c² because they have different variables.

(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)  

(-4c² + 8c²) + (7cd + 4cd) + (8d - 3d)

4c² + 11cd + 5d

The length of a rectangle field if 7/5 of its width. if the perimeter of the field is 240 meters, what are the length and width
trasher [3.6K]
Perimeter of any figure is all its sides summed up

for a rectangle, with two equal pairs, that means, length + length + width + width or   2length + 2width, or  2(length + width)

but we know the length is 7/5 the width

width = w
perimeter = P


\bf P=2\left(\frac{7}{5}w +w \right)\qquad P=240\implies 240=2\left(\frac{7}{5}w +w \right)
\\\\\\
120=\frac{7}{5}w +w\impliedby \textit{let's multiply both sides by 5}
\\\\\\
600=7w+5w\implies 600=12w\implies \cfrac{600}{12}=w

and the length is 7/5 of that
