Answer:

<h2>The answer is 32</h2>

Step-by-step explanation:

3( 2c + d) - 4( c - d) + d²

when c = 1 and d = 3

Substitute the values of c and d into the above expression and solve

We have

3 [ 2(1) + 3 ] - 4 ( 1 - 3) + 3²

<u>Solve the terms in the bracket first</u>

➢ 3( 2 + 3) - 4( - 2) + 9

➢ 3( 5) + 8 + 9

<u>Simplify</u>

➢ 15 + 8 + 9

➢ 15 + 17

We have the final answer as

Hope this helps you

Given △ABC where A(2, 3), B(5, 8), C(8, 3), RS is the midsegment parallel to AC, ST is the midsegment parallel to AB, and RT is

soldier1979 [14.2K]

Since RS is a midsegment parallel to AC, that means R is the midpoint of AB and S is the midpoint of BC. The midpoint formula is:
$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$ . Using the coordinates of A and B, we have:
$R=(\frac{5+2}{2},\frac{8+3}{2})
\\R=(\frac{7}{2},\frac{11}{2})
\\R=(3.5, 5.5)$ . Similarly, S is the midpoint of BC:
$S=(\frac{5+8}{2},\frac{8+3}{2})
\\S=(\frac{13}{2},\frac{11}{2})
\\S=(6.5, 5.5)$ .
Since ST is a midsegment parallel to AB, then T must be a midpoint of AC:
$T=(\frac{2+8}{2},\frac{3+3}{2})
\\T=(\frac{10}{2},\frac{6}{2})
\\T=(5,3)$ .
Now that we have the coordinates of each point we can find the length of each segment using the distance formula:
$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
For ST:
$d=\sqrt{(6.5-5)^2+(5.5-3)^2}
\\=\sqrt{(1.5)^2+(2.5)^2}
\\=\sqrt{2.25+6.25

\\=\sqrt{8.5}=2.9 \neq 4$
For RT:
$d=\sqrt{(3.5-5)^2+(5.5-3)^2}
\\=\sqrt{(-1.5)^2+(2.5)^2}
\\=\sqrt{2.25+6.25}
\\=\sqrt{8.5}=2.9 \neq 5$
For RS:
$d=\sqrt{(3.5-6.5)^2+(5.5-5.5)^2}
\\=\sqrt{(-3)^2+(0)^2}
\\=\sqrt{9+0}=\sqrt{9}=3$

HELP PLEASEE<br> I’m stuck

Sever21 [200]

Answer:

:-):-)

Step-by-step explanation:

1) p<1000

2)p>500

3)By combining the above two, we get: 500<p<1000

Andre will agree as he thinks that the no. of paper clips in the box is less than 1000. But lin will not as she thinks that the no. of clips is more than 500.

4)This time, they both will agree as the no. of paper clips is more than 500 but less than 1000.

Why is 59.47 > 59.3?

Charra [1.4K]

Because .4 is bigger than .3.

the closer you are to .9 the more closer you are to a positive 1
