Answer:
6x^2 - 19x + 10 is the answer
Step-by-step explanation:
Lets use the FOIL method to expand,
(2x - 5)(3x -2)
2x * 3x + 2x * -2 + -5 * 3x + -5 * -2
This is the expanded version of the expression above!
here is a better way of explaining it,
(2x - 5) is the first equation now lets split it up
now its 2x and -5!
now you just multiply 2x and -5 to the second equation (3x - 2)
makes sense?
Lets Simplify it,
2x * 3x + 2x * -2 + -5 * 3x + -5 * -2
6x^2 - 4x - 15x + 10
6x^2 - 19x + 10
(tip: DON'T FORGET SAY ^2 because there are 2x's in the (2x*3x) part!)
Now you just simplify!
So as a result the answer is,
6x^2 - 19x + 10
Hope this helps :)
Answer:
4
Step-by-step explanation:
Because the powers have the same base of 2, we can apply the index law:
Therefore,
Answer: x = -6
Step-by-step explanation:
4x−3y=−24
x intercept is the value ox when y = 0
4x−3y=−24
4x−3*0=−24
4x = -24
x = -6
Answer:
2/8
Step-by-step explanation: Because there is a total of two parts so it should be the answer
Answer:
C. 772.5 kg
Step-by-step explanation:
We have been given that a hot air balloon holds 4,328 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter.
To find the amount of helium in the balloon, we will use density formula.
Upon substituting our given values, we will get:
Upon rounding our answer to nearest tenth, we will get:
Therefore, the balloon contains 772.5 kilograms of helium and option C is the correct choice.
