9(m - 3) + 3m = 7m + 43

frozen [14]

$\begin{gathered} 9(m-3)+3m=7m+43 \\ \text{Multiply the parenthesis by 9 and you have} \\ \\ (9\times m-9\times\lbrack-3\rbrack)+3m=7m+43 \\ \text{Next you have} \\ 9m-27+3m=7m+43 \\ \text{Note that the 9 multiplies the m to get 9m,} \\ \text{and the 9 also multiplies the negative 3 to arrive at negative 27.} \\ \text{After applying 9 to open the parenthesis, you now have } \\ 9m-27+3m=7m+43 \\ \text{You collect like terms. In this case all expressions that have m are like terms} \\ \text{The ones that does not have m are also like terms but, separate} \\ \text{Collect like terms with m on to the left hand side} \\ 9m+3m-7m=43+27 \\ \text{Note that whenever a positive number moves over across the sign of equality,} \\ it\text{ becomes a negative number and vice versa.} \\ \text{Hence 7m has moved and now becomes -7m} \\ \text{Also -27 has moved and now becomes +27} \\ 9m+3m-7m=43+27 \\ 5m=70 \\ \text{Divide both sides by 5 to eliminate it from the left side} \\ \text{and hence m would now stand alone} \\ \frac{5m}{5}=\frac{70}{5} \\ m=14 \end{gathered}$

In this rectangle, find m angle DEC.<br> Please help me!!!!

notsponge [240]

Answer:

118°

Step-by-step explanation:

EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)

The total sum of angle EDC and ECD is 31 + 31 = 62°

The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.

180 - 62 = 118°

Factorise completely:<br> (a) 8m - 50 n2

Sever21 [200]

Answer:

2(4m-25n2)

Step-by-step explanation:

To factorise,we will have to know the value that can divide both variables given

But based on this question,we have different variables that is m and n

So we don't have to deal with that but with the numbers which means that we will only deal with the numbers ignoring the letters

8m-50n2

So the only number that can divide the two is 2

2(4m-25n2)

This cannot be solved further so the final answer is 2(4m-25n2)

I hope this will help you
