Answer:

y=4x^2+12x+9

Step-by-step explanation:

Perform the square of the binomial, combine like terms, and then write the remaining expression in decreasing order of powers of x:

y=(2x+3)^2\\y=(2x+3)\,(2x+3)\\y=4x^2+6x+6x+9\\y=4x^2+12x+9

The simplification form of the expression (1.93 × 10⁷) − (9.7 × 10⁶) is

9.6×10⁶ and the correct order is shown in the picture.

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

\rm =\left(1.93\times \:10^7\right)-\left(9.7\times \:10^6\right)

\rm =\left(1.93\times \:10^7\right)-\dfrac{10}{10}\left(9.7\times \:10^6\right)

\rm =\left(1.93\times \:10^7\right)-\left(0.97\times \:10^7\right)

= \rm (1.93-0.97)\times 10^7

= 0.96\times 10^7

= \dfrac{10}{10}(0.96\times 10^7)

= 9.6×10⁶

Thus, the simplification form of the expression (1.93 × 10⁷) − (9.7 × 10⁶) is

9.6×10⁶ and the correct order is shown in the picture.

Answer:

RS = 15 and RT = 18, then ST = 3!   :D

Step-by-step explanation:r = 1 --> s=15 & t=18 so st = 270

r = 3 --> s = 5 & t = 6 so st = 30

r = 5 --> s = 3 & t = 3.6 so st = 10.8

etc

==============

In literal terms:

s = 15/r

t = 18/r

Hope this helped, I'm just in middle school but I'm sure of this! :D
