Answer:

I believe your answer is 8.

Step-by-step explanation:

Because you plug the value in the problem so:

4 - 3(3) +5 + 8=

4 - 9 + 5 + 8

 4 - 9 = -5 + 5 + 8

- 5 + 5 = 0 + 8

0 + 8 = 8

Hope my answer has helped you and if not i'm sorry.

Exercise 21
Lina20 [59]

Answer:

see explanation

Step-by-step explanation:

area of Δ ABC is calculated as

A = \frac{1}{2} bh ( b is the base and h the height )

Here b = 4x - 6 and h = 2x - 3 , then

A = \frac{1}{2} (4x - 6)(2x - 3) ← expand using FOIL

   = \frac{1}{2}(8x² - 24x + 18) ← distribute

    = 4x² - 12x + 9

----------------------------------------------------------

Area of rectangle CBFG is calculated as

A = lb ( l is length, b is breadth )

Here l = 4x - 6 and b = 3x - 2, then

A = (4x - 6)(3x - 2) ← expand using FOIL

   = 12x² - 26x + 12

----------------------------------------------------------

Area of trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂)

where h is the height and b₁, b₂ the parallel bases

Here h = 2x - 3, b₁ = 4x + 1, b₂ = 2x + 3 , then

A = \frac{1}{2} (2x - 3)(4x + 1 + 2x + 3)

   = \frac{1}{2} (2x - 3)(6x + 4) ← expand using FOIL

   = \frac{1}{2} (12x² - 10x - 12) ← distribute

   = 6x² - 5x - 6

Given the rational number :

0.9, -2/1/2, 0.25, -3/4

Converting all to decimal;

0.9 = 0.9

-2 1/2 = - 2.5

0.25 = 0.25

-3/4 = - 0.75

Which expression is equivalent to (m^8n^−4)^14 ?
umka2103 [35]

Which expression is equivalent to (m^8\times n^-4)^ 1/4

Answer:

m^2/n

Step-by-step explanation:

Given.

I assume this is your expression:

The expression is =(m^{8} \times n^{-4} )^{\frac{1}{4} }

Now simplify the expression by multiplying the power.

=(m^{8\times \frac{1}{4}} \times n^{-4\times \frac{1}{4}}} )

=(m^{2} \times n^{-1} )

=\frac{m^{2}}{n}

So, the expression is equivalent to \frac{m^{2}}{n}

Fixed Object Involved in Collision Number of Collisions Pole/post 1,416 Culvert/curb/ditch 2,516 Shrubbery/tree 2,585 Guardrail
Genrish500 [490]

Answer:

0.1358 = 13.58% probability of a fatal collision with a pole or post

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

1416 collisions with pole or post.

1416 + 2516 + 2585 + 896 + 947 + 231 + 1835 = 10426 total collisions.

a. What is the probability of a fatal collision with a pole or post?

p = \frac{1416}{10426} = 0.1358

0.1358 = 13.58% probability of a fatal collision with a pole or post
