First you take 8 common which is the highest number that can divide both the nimbers, then u can also take t common...now taking a negative common is up to you. so I did all this in the second step. Then you just set it equal to 0. t=0 and 15/2

If you want to learn to factor fractions, it's easy
for example
-16×(t²+15/2t)
now -16×t² is -16t² , but -16×15/2t, first you factor -16 with number that is above the line, it would be -16×15t, and then divide with a number below the line
so it's -16t²-(16×15)/2t= -16t²-120t
and next solve
0=-16t²-120t
0=8t²(2t-15)
8t²=0. 2t=15
t1=0. t2=15/2
there are two solutions

If side A is twice as long as B and C is 25 using the Pythagorean Theorem,What are the lengths of side A and B? Round to the nea
777dan777 [17]

Answer:

<u>The lengths of side A is 22.4 and B is 11.9</u>.

Step-by-step explanation:

Given:

If side A is twice as long as B and C is 25 using the Pythagorean Theorem.

Now, to find the lengths of side A and B.

Let the side B be x.

So, the side A be 2x.

Side C = 25.

Now, to solve by using Pythagorean Theorem:

A² + B² = C²

(2x)^2+(x)^2=(25)^2

4x^2+x^2=625

5x^2=625

<em>Dividing both sides by 5 we get:</em>

x^2=125

<em>Using square root on both sides we get:</em>

x=11.18.

<u>B rounding to the nearest tenth =  11.9.</u>

Now, to get A by substituting the value of x:

2x\\=2\times 11.18\\=22.36.

<u>A rounding to the nearest tenth =  22.4.</u>

Therefore, the lengths of side A is 22.4 and B is 11.9.

Solve the system using elimination.
expeople1 [14]

Answer:

(- 9, - 9)

Step-by-step explanation:

Given the 2 equations

3x - 4y = 9 → (1)

- 3x + 2y = 9 → (2)

Adding (1) and (2) will eliminate the term in x

(1) + (2) term by term

(3x - 3x) + (- 4y + 2y) = (9 + 9)

0 - 2y = 18

- 2y = 18 ( divide both sides by - 2 )

y = - 9

Substitute y = - 9 into (1) or (2) and evaluate for x

(1) → 3x + 36 = 9 ( subtract 36 from both sides )

3x = - 27 ( divide both sides by 3 )

x = - 9

Solution is (- 9, - 9)

Mr. Hinckley owns 83 acres of land, he divides the land into eight equal sections to sell to eight buyers which phrase describes
anygoal [31]

Alright, lets get started.

Mr. Hinckley owns 83 acres of total land.

He divides the land into eight equal sections to sell to eight buyers.

It means, we could find the land each buyer receives by dividing total land by 8.

So, each buyer receives land = \frac{83}{8}

So, each buyer receives land = 10.375 acres

So, the answer is 10.375 acres lands received by each buyer. : Answer

Hope it will help :)
