Pls help!!!! Thank you

Step-by-step explanation:

4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0

∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5

x = (-(-3) ± √5)/2(1) = (3 ± √5)/2

x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)

Answer:

See below

Step-by-step explanation:

Since the shape of the truck isn't given and the volume, we will make some assumptions. You can solve this problem if you have the complete one by following the same procedure. Lets assume:

Shape of Truck is Cuboid

The dimensions of the Truck is 9 by 9 by 9

First, we need to find the volume of the cuboid truck.

Volume is basically 3 dimensions multiplied together. So that would be:

Volume of Truck = 9 * 9 * 9 = 729 cubic feet

Each box has a volume of 9 cubic feet. To get number of boxes that evenly fit the truck, we would need to divide the truck's volume by volume of each box.

729/9 = 81 boxes

Answer:

60

Step-by-step explanation:

trangles always equal 180 degrees on the inside angles

180-75-45 = 60

Answer:

length=2×width

2width×width=128

2width ²/2. =128/2

width². =64

width=8feet

Answer:

Below.

Step-by-step explanation:

The Domain is all real values of x.

The range is  -6 ≤ f(x) < ∞.

( I cant see the minimum value very clearly but I think its -6).

Minimum -6 Maxm ∞.

Decreasing from f(x) = -∞ to f(x) = -6.

Increasing from f(x) = -6 to ∞.

Answer:

7: 100

8: 40

9: 74

Step-by-step explanation:

Answer:

7. x= 100 8. x= 40 and 9. x= 74

Step-by-step explanation:

x + 45 +35=180(sum of angle of triangle )

or, x+ 80=180

or, x=180-80

or, x=100

same process as above for all

Answer:

S=9

Step-by-step explanation:

10[tex]\frac{1}{2}[/tex] - 1[tex]\frac{1}{2}[/tex] = 9

Answer:

s=9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

s+3/2=21/2

Step 2: Subtract 3/2 from both sides.

s+3/2−3/2=21/2−3/2

s=9

Answer:

the answer is -3/2.

Step-by-step explanation:

Answer:

120 yards

Step-by-step explanation:

Answer:

360 ft.

Step-by-step explanation:

You multiply the number of total yards, which is 120, by 3 to get feet.

Answer:

25%

Step-by-step explanation:

There's 3 tablespoons of nuts and 1 tablespoon of berries, so 1/4 tablespoons is berries.

Answer:

To sum up, we looked at the important amount devided by the total amount. Finally we solved for p. Which gave us p=75. Furthermore 75 percent of the trail mix is made up out of berries.

Step-by-step explanation:

So the main equation with percentages is W/G = p/100.

So First we look at G. G describes the total amount. In this case the total amount of teaspoons is four. Four because we have three tablespoons of berries and one tablespoon of nuts. That is four tablespoons.

Now we can go further to find out what W is. 2 is the important amount. In the question we are supposed to look at the amount of berries is the trail mix. Which gives us the value three.

So far our equation has no unknowns anymore 3/4=p/100. We multiply both sides of the equation with 100 3*100/4=p. Thus p = 300/4=150/2=75.

Answer:

The percent of change in the population was of 25%.

Step-by-step explanation:

Percent change:

The percent change is given by the change multiplied by 100, and divided by the initial value.

A towns population went from 40,000 to 50,000.

Change: 50000 - 40000 = 10000

Initial value: 40000

10000*100/40000 = 25%

The percent of change in the population was of 25%.

Answer: 3/5 of the park population is female, or 60 percent. How? 80:200 can be simplified to 40:100, and this in fraction form is 40/100. We can further simplify it by dividing both by 10 to get 4/10, and then by 2 to get 2/5. 5 - 2 = 3, so 3/5 is the answer.

I hope this helps!

Answer:

x=4, x=-4

Step-by-step explanation:

x^2-16=0

Add 16 to both sides;

x^2-16+16=0+16

Simplify;

x^2=16

x=[tex]\sqrt{16}[/tex], x[tex]-\sqrt{16}[/tex]

[tex]\sqrt{16}[/tex]

=4

factor the number;16

[tex]\sqrt{4^2}[/tex]

=[tex]\sqrt{4}[/tex]

-[tex]\sqrt{16}[/tex]

Factor the number 16;

[tex]\sqrt{4^2}[/tex]

=-4

Answer:

Multiply the first equation by 6.

5x-10= 3x+10

5x-3x= 10+10

2x÷2= 20÷2

x= 10

Step-by-step explanation:

as AD bisects them they will be two equal parts so

5x-10=3x+10

5x-3x=10+10

2x=20

divide both sides by 2 and

x=10
