5(t+3)+2(3t+4)-(5t-3)

Answers

Answer 1
Answer: 5(t+3)+2(3t+4)-(5t-3)
First, you need to use the distributive property.
5t+15+6t+4-5t+3
Next, you add/subtract like terms
5t+6t-5t=6t
15+4+3=22
So, you are left with:
6t+22

Hope this helped! If you have any other questions pertaining to this, please ask!
Answer 2
Answer: The answer is 6t + 26                  In the process of solving this problem you will use mathematical properties , adding , subtracting , dividing , and simplifying. 

My reason being is because , 1st you solve | 2 *3t + 13 , than look at the equation again :

it's really , (5*3t) + 2 *( (3t+4) ) - ( 5t - 3 ) .  This is how I got my answer , by pulling out like terms , which happen to be : 6t + 26 = 2 * (3t+13).

The last step to the answer is below :

2 * (3t + 13) .

I really hope that this helps you out a lot, have a nice day :)

A vehicle travels a distance of 5t4 − 10t2 + 6 miles in t + 2 minutes. What is the vehicle's speed?

Answers

Let distance be s and velocity be v
s = 5t⁴ - 10t² + 6
We know velocity is the change in distance per unit time, so
v = ds/dt
v = 20t³ - 20t

Answer:

The speed is 5t^3 - 10t^2 + 10t - 20 + 46/(t+2) miles per minute

Which products result in a perfect square trinomial? Check all that apply.A=(–x + 9)(–x – 9)
B=(xy + x)(xy + x)
C=(2x – 3)(–3 + 2x)
D=(16 – x2)(x2 – 16)
E=(4y2 + 25)(25 + 4y2)

Answers

The correct answers are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

Explanation:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same.  For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order.  The same is true of (4y² + 25)(25 + 4y²).

Answer:

A and E and C

Step-by-step explanation:

A perfect square trinomial can be written as the square of a binomial.
