If the expression ax( 2x+y-5) simplifies to 6x^2 + 3xy-15x, what is the value of a

a = 3

Step-by-step explanation:

Expand the given expression and compare like terms on both sides

Given

ax(2x + y - 5) = 6x² + 3xy - 15x ← distribute left side

2ax² + axy - 5ax = 6x² + 3xy - 15x

Compare coefficients of the x- terms, that is

- 5a = - 15 ( divide both sides by - 5 )

a = 3

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
