6(m-1)=3(3m+5)<br> what does m=

love history [14]

Answer:

m = - 7

Step-by-step explanation:

Given

6(m - 1) = 3(3m + 5) ← distribute parenthesis on both sides

6m - 6 = 9m + 15 ( subtract 9m from both sides )

- 3m - 6 = 15 ( add 6 to both sides )

- 3m = 21 ( divide both sides by - 3 )

m = - 7

In paralelleogram ABCD, diagnosis AC and BD intersect at point E, BE=X2-40 and DE= 6x. What is BD?

Alchen [17]

Answer:

Length of BD = $x^2$ +6x - 40

Step-by-step explanation:

In parallelogram ABCD , diagonals AC and BD intersect at E .

In a parallelogram , the two opposite sides are parallel and equal in length.

Also opposite angles of a paralleogram are equal .

Here the length of the parts of a diagonal is given.

BE = $x^{2}$ - 40

DE = 6x

Since the length of whole diagonal is the sum of the lengths of the parts of the diagonal ,

Length of BD = BE + DE

= $x^{2}$ -40 + 6x

Length of BD = $x^2$ +6x - 40
