The way it's written it's
Simplify the following:
7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5
Grouping like terms, 7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5 = 7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5):7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5)
4 X^2 + 2 X^2 = 6 X^2:
7 X^3 + 6 X^2 + (3 X + X) + (2 + 5)
3 X + X = 4 X:
7 X^3 + 6 X^2 + 4 X + (2 + 5)
2 + 5 = 7:Answer: 7 X^3 + 6 X^2 + 4 X + 7
For each choice of the first two digits you have 10<span> choices for the third digit. Thus you have 10x10x10 = 1000 choices for the first three digits. Finally you have </span>10<span>choices for the fourth digit and thus there are 10x10x10x10 = </span>10 000<span> possible 4 digit combinations from </span>0-9<span>.</span>
Answer:
The price of the kilogram of cookies is $ 1.8
Step-by-step explanation:
Call x the price of the kilogram of candy and call y the price of kilogram of cookies
Then we know that
We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy
So
We solve this equation for x and then we substitute it in the first equation.
We are given expression: 
.
Tyna simplified the given expression to 
.
Explanation: In order to simplify , Tyna need to simplify rational expression 
.
On dividing top and bottom by 3, we get 
.
Which Tyna got correct.
Now she need to simplify 
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be 
.
<h3>So, the final answer should be
.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
Answer:
A solution to a linear system, or simultaneous solution, is an ordered pair (x, y) that solves both of the equations. In this case, (3, 2) is the only solution.
