x(x+2)=2(4)
x²+2x=8
minus 8 both sides
x²+2x-8=0
factor

What is 3x+2x+6=-18​
maksim [4K]

Answer:

x = -4.8

Step-by-step explanation:

combine like terms

3x + 2x + 6 = -18

5x + 6 = -18

isolate the terms with the x variable

5x + 6 - 6 = -18 - 6

5x = -24

isolate x

5x/5 = -24/5

x = -4.8

CAN SOMEWON HELP ME PLZZZ I DONT GET IT
klio [65]

Hey there! I'm happy to help!

We want to put this 0.002 into scientific notation, where you put it as a one digit number multiplied by 10 raised to a certain power.

If we move the decimal to the right 3 times, we will have 2. We will multiply this 2 by 10^-^3 to show that it is still equal to 0.002.

So, the mass of the mustard seed is 2×10^-^3.

Now, we multiply this mustard seed mass by the number of mustard seeds to find the weight of all of the mustard seeds combined.

(2×10^-^3)×(4.3602×10^4)

Let's round 4.3602 to the nearest whole number, which is 4. We multiply those two together.

2×4=8

And we multiply the two exponents. When multiplying them, you add the numbers in the exponent. -3 and 4 combined gives us 1, and 10 the first power is just 10.

So, a good estimate for the mass of the mustard seeds is 80 grams, which is the same as (2×10^-^3)×(4×10^4)=8×10^1

Have a wonderful day! :D
