Answer:

D) 2x²+4x-30

Step-by-step explanation:

You would multiply x and 2x; x and -6; 5 and 2x; 5 and -6

(x)(2x) = 2x²

(x)(-6) = -6x

(5)(2x) = 10x

(5)(-6) = -30

Now just put it back in the order that it was listed in the equation starting with (x)(2x)

This would give you 2x²-6x+10x-30

Simplify even further to get 2x²+4x-30

To get to the next term in this sequence, multiply the last term by 2.5. What is the value of the next term?
nirvana33 [79]
<h3><u>Question:</u></h3>

"To get the next term in the sequence,multiply the last term by 2.5 . What is the value of the next term?

1 , 2.5 , 6.25, 15.625, ..."

<h3><u>Answer:</u></h3>

The value of the next term is 39.0625

<h3><u>Solution:</u></h3>

Given that the series is 1 , 2.5 , 6.25, 15.625

When we divide 2nd term by first we get 2.5 , similarly for other successive number when we divide them with their preceding number we get a value of 2.5

So, all the successive numbers are 2.5 times of their previous number  

1 \times 2.5 = 2.5\\\\2.5 \times 2.5 = 6.25\\\\6.25 \times 2.5 = 15.625\\\\15.625 \times 2.5 = 39.0625

So the value of next term is 39.0625

What is the solution of 3+ x-2/x-3 less than or equal to 0
bagirrra123 [75]

Answer:

The solution set consists of all the real numbers smaller than or equal to 11/4:

x\leq \frac{11}{4}

Step-by-step explanation:

We need to solve for x (that means isolate x on one side of the inequality symbol) in the following inequality:

3+\frac{x-2}{x-3} \leq 0\\\frac{x-2}{x-3} \leq -3\\x-2\leq -3\,(x-3)\\x-2\leq -3x+9\\x+3x\leq 9+2\\4x\leq 11\\x\leq \frac{11}{4}
