Answer:

x^3+8x^2+2x+1

Step-by-step explanation:

Combine like terms (terms with the same exponent).

x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1

"Standard form" means to list terms so the exponents go from high to low (descending order).

Jackson’s age was 2/fifth of the age he will be 20 years from now seven years ago. How old is Jackson now?
Margaret [11]
Let's say Jackson's age now is x.

In 20 years, (so 20+x), Jackson seven years ago will be 2/5ths of that age.

So 2/5(20+x)=x-7

Then you solve the equation
8+2/5x=x-7
15=3/5x
x=25
Jackson is 25 years old. 

Let's check our answer! In 20 years, Jackson will be 45. 7 years ago, he was 18. 2/5 of 45 is 18. Our answer is correct!

dsp73

Answer:

There are 60 total questions on the course exam.

Step-by-step explanation:

Given that:

Number of questions finished by Jasmine = 12

Percentage shown on the bar = 20%

The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.

Let,

x be the total number of questions on the course exam

20% of x = 12

\frac{20}{100}x=12\\0.2x=12

Dividing both sides by 0.2

\frac{0.2x}{0.2}=\frac{12}{0.2}\\x=60

Hence,

There are 60 total questions on the course exam.
