He is not correct. If this is to be an equilateral triangle then all the angles must be the same measure. That means that 180/3 = 60°. They all have to equal 60°. If one of the angles measures 4x-12, then 4x-12=60. Solving for x, we will add 12 to both sides to get 4x=72. x here is 18. For the other angle measuring 2x+26, we would do the same. 2x+26=60. Subtract 26 from both sides to get 2x= 34 and x = 17. He was way off.
G(x)=4x^2+40x
g(x)=4(x^2+10x)
g(x)=4(x^2+10x+25)-4(25)
g(x)=4(x+5)^2-100
the missing numbers that should be filled in the blanks are:
4, 5, 100
<u>Answer:</u>
$450
<u>Step-by-step explanation:</u>
We are given that Brenda's Boards manufactures skateboards and sells them for $45 each.
The wheels in the skateboard are for $3, plastic board for $1, paint for $1 and $10 for the labor.
We are to find the total revenue generated if they sell 10 skateboards.
For that, we just need to multiply the price of a skateboard by 10.
Total revenue = 10 x 45 = $450
76.48
- 65.00
----------
$11.48
The answer for how much of a markdown would be 15%
The inequality
76.48 is greater than or equal to 65 + 15%
The Tangent Line Problem 1/3How do you find the slope of the tangent line to a function at a point Q when you only have that one point? This Demonstration shows that a secant line can be used to approximate the tangent line. The secant line PQ connects the point of tangency to another point P on the graph of the function. As the distance between the two points decreases, the secant line becomes closer to the tangent line.
