Help!!!!!!!!!!!! What is P(2)? 7 14 21 28

Lubov Fominskaja [6]

P(2) is 14, because the 2 represents where the number in t, so you have to find the number under 2, so you get 14.

*100 points* What is the value of x in these polygons?

Effectus [21]

Answer and Step-by-step explanation:

$Greetings!$

$Let's~answer~your~question!$

$Since~ we~ know~ that ~these ~two~ are~ similar, ~it ~is ~also~ given ~that~ corresponding\\ parts ~of ~the~ triangle~ are ~proportional.~ In ~result,~ you~ can~ set~ the~ proportions~\\something~ like~ this:$

$\frac{16}{32}= \frac{12}{24}$

$Now,~from~ here, you~ can ~figure~ out~ that~ the~ ratio~ of ~the ~larger ~triangle~ to ~the \\~smaller~ triangle~ is ~.75:1$

$You~can~ then~ apply~ this~ to~ the~ side ~of ~x-1 ~and ~set~ up ~the~ equation.$

$.75(x-1)=6$

$Now,~solving~ the~ equation,~ you~ get~ x=9.~ Substitute~ that~ into~ x-1~ and~ you\\ get~ 8 ~as ~that~ side~ length.~ To~ check, compare:$

$\frac{8}{6}=\frac{32}{24}$

$Thus,~the~value~of~x~is=9.$

$Hope~my~answer~helps~you!~Have~a~blessed~day~ahead!$

what is a correct first step in solving the inequality –4(3 – 5x)≥ –6x 9? –12 – 20x ≤ –6x 9 –12 – 20x ≥ –6x 9 –12 20x ≤ –6x 9 –1

suter [353]

we have

$-4(3-5x) \geq -6x+9$

Step 1

Applying the distributive property in the left side ( Multiply the factors on the left side)

$-4(3-5x) \geq -6x+9\\- 4*3+4*5x\geq -6x+9\\-12+20x\geq -6x+9$

therefore

the answer is

$-12+20x\geq -6x+9$

What are the extremes of the followin proportion? 3/15=12/60

cupoosta [38]

Answer:

3 and 60

Step-by-step explanation:

A proportion is a mathematical expression in which two ratios are shown to be equal.

Hence

$a/b = c/d \\$ is proportion .

it can be also written as a:b= c:d

The four part a,b,c,d can be divided into two groups

means : b and c are means
extremes: a and d are extremes

based on above discussion

in proportion 3/15=12/60

3 is in position of a

and

60 is in position of d

Thus, 3 and 60 are extremes in 3/15=12/60 proportion.
