What is the solution to -6 + 5(1-x) = - 13 – 7 x?

x=-6

Step-by-step explanation:

1) Using the distributive property distribute the 5 to the equation in the parenthesis

2) Combine the -6 and 5

3) Add 1 to both sides.

4) Add 7x to both sides

5) Divide both sides by 2 to isolate the x.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
