The area (in square feet) of the school sign can be represented by $15x^2-x-2$ . a. Write an expression that represents the length of the sign. length: ft Question 2 b. Describe two ways to find the area of the sign when $x=3$ . 1. Substitute for into the expression for the area $15x^2-x-2$ , then simplify. 2. Substitute for into the expressions for the length $\text{(}$ $\text{)}$ and width $\left(3x+1\right)$ , simplify each, then multiply these two numbers.

70,000 + 6,000 + 800 + 30

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
