How I can answer this question, NO LINKS, if you answer correctly I'll give u brainliest!

Simplifying

0.25k + 1.5 + -1k + -3.5 = 0

Reorder the terms: 1.5 + -3.5 + 0.25k + -1k = 0

Combine like terms: 1.5 + -3.5 = -2 -2 + 0.25k + -1k = 0

Combine like terms: 0.25k + -1k = -0.75k -2 + -0.75k = 0

Solving -2 + -0.75k = 0

Move all terms containing k to the left, all other terms to the right.

Add '2' to each side of the equation. -2 + 2 + -0.75k = 0 + 2

Combine like terms: -2 + 2 = 0 0 + -0.75k = 0 + 2 -0.75k = 0 + 2

answer = -0.75k-2

-0.75k-2.0

Step-by-step explanation:

0.25k+1.5-k-3.5

0.25k-(1)k+1.5-3.5

0.25k-1.0k-2.0

-0.75k-2.0

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.

y=1/4x-4
