Which expression shows a sum of five terms?
a: 5(x + 5)
b: 5x
c: x5
d: 5 + x + 5 + x + x

Answer with Step-by-step explanation:

We are given 4 expressions and we have to determine which expressions shows a sum of five terms.

A: 5(x + 5)

=5x+25  (distributing 5)

This contains sum of only two terms

B: 5x

It contains only 1 term

C:

It also contain only one term

D: 5 + x + 5 + x + x

It contains 5 terms 5,x,5,x and x

and gives the sum of these five terms

Hence, Correct option is:

D: 5 + x + 5 + x + x

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
