First we need to find the scale factor that 5 has decreased by

5/3=0.6

Then multiply the length of the birdhouse shadow by that scale factor

12*0.6=7.2 feet

So the new birdhouse shadow length is 7.2 feet

Hope this helps!

For the equation: 3x+1=2x+7 what are the 1 st and 2 nd opposite operations?

qaws [65]

Answer:

Step-by-step explanation:

3x +1 = 2x +7 subtract 1 from both sides ( first)

3x +1 -1 = 2x + 7 -1

3x = 2x + 6 subtract 2x brom both sides (second)

3x -2x = 2x -2x +6

5x = 6

Find the quotient of quantity of 4 times x to the 3rd power minus 12 times x to the 2nd power plus 8 times x all over negative 4

I hope I read it correctly and address as such.
Anywho, this is how my teacher taught me to deal with a question like that. Basically just break up the polynomial on top and divide each part separately by the monomial denominator.

Steven saves $0.30 each week.

barxatty [35]

after 4 weeks:

.3*4= 1.2 saved

then it is doubled

1.2*2 = 2.40

8 weeks

he will have saved for 4 more weeks ( week 5 6 7 8)

4 * .3 = 1.2 saved

2.4 + 1.2 = 3.6 saved

then it is doubled

3.6 * 2 =7.20

he will have saved for 4 more weeks ( week 9, 10, 11, 12)

4 * .3 = 1.2 saved

7.2+ 1.20=8.40

then it is doubled

8.4*2 = 16.8

He will have 16.80 after 12 weeks
