Answer:

-8±10x

Step-by-step explanation:

you will follow BODMAS

B=bracket

O= off

D=division

M=multiplication

A=addition

S=subtraction

2×3=6

7×2=14

[6-14±10x-8]÷[x-2]

14±8=22

6-22=-16

[-16±10x]÷[x-2]=-8±10x

Andrej [43]

Answer: 210

Step-by-step explanation:

We know that the number of combinations of n things taken r at a time is given by :-

C(n,r)=\dfrac{n!}{r!(n-r)!}

So, number of ways to select 3 plants out of 7 = C(7,3)=\dfrac{7!}{3!4!}=\dfrac{7\times6\times5\times4!}{6\times 4!}=7\times5=35

Also number of ways to arrange them in 3 positions = 3! = 6

Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)

= 35 x 6

=210

Hence, required number of ways = 210

Find the measure of the angles indicated
GalinKa [24]

Both angles have a measure of 125°.

<h3>How to find the measure of the angles?</h3>

Assuming the two horizontal lines are parallel, we know that the measure of the two indicated angles must be the same one.

Then:

-1 + 14x = 12x + 17

Now we need to solve this for x:

14x - 12x = 17 + 1

2x = 18

x =18/2 = 9

Now that we know the value of x we can replace it in any of the expressions for the angles:

-1 + 14*9 = 125°

Both angles have a measure of 125°.

What to do when you multiply or divide both sides of an inequality by a positive value
wolverine [178]

Answer:

It is the same as a normal equation with an equal sign. If you were to divide by a negative, the inequality sign would flip to point to the other side of the inequality.
