Express the following equation in the form ax^2+bx+c=0:
(4a+3)^2=(a+5)(a−2)

Answers

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

15a² + 21a + 19 = 0

Help plssss lolllllll

Answers

Answer:

Step-by-step explanation:

you want to set it up like this

8/20 and 6/2x-1

then you cross multiply

so 8(2x-1) = 16x-8

and 20*6 = 120

then you do 120= 16x-8

add 8 to both sides (you want x by it's self so to get rid of a -8 you have to add 8)

128= 16x

(divide both sides by 16)

128/16= 8

8=x

What is the value of 16.43 – 1.043

Pls show the work of how you did it

Answers

Answer:

15.387

Explanation:

16.43
- 1.043
————
15.387

Decimals are cool because you can add zeros to the end of them, and they will still be the same number.

16.43 = 16.430

I add the zero to the thousandths place because I am subtracting a number from 16.430 that has a number in the thousandths place. When you line the two numbers up to subtract you want to make sure they have an equal amount of decimal places.

1 6. 4 3 0 <— you now are ready to subtract.
- 1 . 0 4 3 I lined up the numbers in the
—————— ones, tenths, hundredths + Thousandths place. I drop the decimal point down.

Start from the rightmost digit.
You can’t subtract 3 from 0, so you borrow ten from the left.
3-1 =2. Cross out 3 and write 2 above it.
You add 10 to 0. 10+0=10. Cross out 0 and write 10 above it.
You can subtract 3 from 10 now. 10-3=7.

2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
. 7

You can’t subtract 4 from 2, so you borrow from the left again.
4-1=3. Cross out 4 and write 3 above it. 2+10=12. Cross out 2 and write 12 above it.
12 - 4 = 8.
This is what that looks like:

12
3 2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
. 8 7

3 - 0 = 3.
6 - 1= 5.
1 - 0 (as there is no digit in the tenths place) = 1

12
3 2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
1 5. 3 8 7

So 16.43-1.043= 15.387

5/12

Step-by-step explanation:

Hello, I am no math expert so take this with a grain of salt. Tan=Opposite/Adjacent. Side ON is opposite and side MN is Adjacent. This would mean that the ration would be 5/12. I hope that helped!

Answer:

Since 5 is in most of the answers, I´m guessing that 5 is the length of the short leg. The answer is C

Step-by-step explanation:

In SohCahToa, Sine, Cos, and Tan all have a formula. Since your looking for tan, you would find the sides that are opposite and adjacent to the hypotenuse. And since tan is opposite over adjacent, it would be 5 over 12.

Sine=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent
