Answer:

The first option

Step-by-step explanation:

We are doing height above shadow height. Since the telephone poll is 40 feet high with a 32 feet shadow, it is 40/32. We know the sign casts a 12 1/2 shadow, so this will be our denominator. h is our unknown, so we will have h / 12 and a half as our second fraction for our ratio.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Help please !!:) For y =3x -2x^2 +5x^3 show how to find the value for y when x = 3
victus00 [196]

y = 3x-2x∧2+5x∧3

When we replace x with value 3 we get

y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126

good luck!!!

<span>4x(x) + 3(2x) and 4x2 + 6x  => 4x^2 + 6x and 4x^2 + 6x
5(3x) - 4(3x) and 3x  => 15x-12x=3x and 3x
4(3a) - 2(4a) and 4a2 => 12a-8a=4a and 4a^2
3(3a) + a(3a) and 3a2 + 9a  => 9a+3a^2 and 9a + 3a^2

Can you spot the one which is different?

Choose yes or no to tell if each pair of expressions is equivalent. YES OR NO
AnnyKZ [126]
<h3>Answer:</h3>
  1. no
  2. yes
  3. no
  4. yes
  5. yes
<h3>Explanation:</h3>

The distributive property is useful both for collecting terms and for eliminating parentheses.

1. 3x +1/4 -x +1 1/2 = x(3 -1) +(1/4 +1 2/4) = 2x +1 3/4 ≠ 4x +1 3/4 (no)

2. 2(3x+1) = 2·3x + 2·1 = 6x +2 = 2 +6x (yes)

3. 3(x+1) -(1+x) = (x+1)(3 -1) = 2(x+1) = 2x +2 ≠ 2x +3 (no)

4. 4(x+1)-x-4 = 4x +4 -x -4 = x(4-1) +(4-4) = 3x +0 = 3x (yes)

5. 5.5 +2.1x +3.8x -4.1 = x(2.1 +3.8) +(5.5 -4.1) = 5.9x +1.4 = 1.4 +5.9x (yes)
