Answer:
Step-by-step explanation:
2x*2x=4x^2
2x*3=6x
Keep in mind 4x^2-6x
then next part:
3*2x=6x
3*3=9
6x-9
So totally
(4x^2-6x)-(6x-9)
Minus and minus is equal to +
(4x^2-12x+9)+2=45
4x^2-12x+11=45
-11 on both sides
4x^2-12x=34
X= -17/-2
Hi there! So Andy's total lunch bill was $20 and the drink was 15% of the bill. Percents are parts of 100 and 100 - 15 is 85. That means 85% of the total bill was Andy's food cost. Let's multiply 20 by 85% ti get the cost of his food. 20 * 85% (0.85) is 17. Andy's food costed $17. Here are the answers broken down to be easier to read.
Percent of Andy's bill with food: 85%
Cost of food: $17

Recall that sin(π/2) = 1, and cos(π/2) = 0,
Answer:
<u>5/4</u>
Step-by-step explanation:
Given :
- tanθ = 3/4 = opposite/adjacent
Finding the missing side :
- The hypotenuse must be found
- √3² + 4²
- √25
- 5
Taking the sec ratio :
- secθ = hypotenuse/opposite
- secθ = <u>5/4</u>
