if x is the first, or smallest, of three consecutive integers, express the sum of the integer and the third integer as an algebr

Scrat [10]

Consecutive numbers differ by one. So, if $x$ is the first, the three numbers are

$x,\ x+1,\ x+2$

The sum of the first and third integer is

$x+(x+2)=2x+2$

I’m confused on this one

Mandarinka [93]

Remark

If the lines are parallel then triangle RQS will be similar to triangle RTP

From that, all three lines in one triangle will bear the same ratio to all three lines of the second triangle.

Givens

PQ = 8

QR = 5

RS = 15

ST = x + 3

Ratio

QR/RP = RS/RT

Sub and solve

RP = 5 + 8

RP = 13

RT = 15 + x + 3

RT = 18 + x

5/13 = 15 / (18 + x) Cross multiply

5(18 + x) = 195 Remove the brackets on the left.

90 + 5x = 195 Subtract 90 from both sides.

5x = 105 Divide by 5

x = 105/5

x = 21 Answer <<<<<<<

Step-by-step explanation:

Dod you mean

$= \frac{ {n}^{5} }{ {n}^{ - 2} } \times \frac{ {n}^{2 - 6} }{ {n}^{8} }$

$= {n}^{5 - ( - 2)} \times {n}^{2 - 6 - 8}$

$= {n}^{7} \times {n}^{ - 12}$

$= {n}^{7 + ( - 12)}$

$= {n}^{ - 5} = \frac{1}{ {n}^{5} }$

2. Is x² + 4√x a polynomial ? Justify your answer.

nexus9112 [7]

Answer:

No it isn't

As the variable "x" has root in it which means it isn't a whole number and for a expression to be a polynomial the variable must be whole no.

Hope it helps you!
