Answer:
228
Step-by-step explanation:
We just have to plug in x. So:
36(3)-6+7(3)*2(3)
Simplify:
108-6+21*6
108-6+126
102+126
228
Answer:
The inequality is 2 ≤ x < 8.
A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.
The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.
Answer:
I guess we want to find where is the mistake of Mable, so let's do the steps in the same way as her:
(4x - 3)*(x - 2)^2
1) (4x - 3)*(x - 2)*(x - 2)
2) (4x - 3)*(x^2 - 2*x - 2*x + 4)
3) (4x - 3)*(x^2 - 4*x + 4)
4) 4*x^3 - 16*x^2 + 16*x - 3*x^2 - 12*x - 12
This is different than what she did, she instead of multiplying the terms without x, (-3*4 = -12) she got a -1 there.
If we simplify the above equation we get:
4*x^3 - 16*x^2 + 16*x - 3*x^2 - 12*x - 12
= 4*x^3 + (-16*x^2 - 3*x^2) + (16*x - 12*x) - 12
= 4*x^3 - 19*x^2 + 4*x - 12
Answer:
8/45
Step-by-step explanation:
Define x to be the value of your fraction:
____
When in doubt, you can use your calculator to see which fraction gives you 0.1777777778.
_____
We multiplied by 10^1 above, because there is 1 repeating digit. The power of 10 we use matches the number of repeating digits.
