THEOREM:
- h² = p² + b² where h is hypotenuse, b is base and p is perpendicular.
ANSWER:
[3] By pythagorean theorem,
- x² = 14² + 9²
- x² = 196 + 81
- x² = 277
- x = √277
- x = 16.64 rounded.
[4] By pythagorean theorem,
- x² = 32² + 24²
- x² = 1024 + 576
- x² = 1600
- x = √1600
- x = 40.
[5] By pythagorean theorem,
- (2x)² = 21² – 12.6²
- 4x² = 441 – 158.76
- 4x² = 284.24
- x² = 284.24/4 = 70.56
- x = √70.56
- x = 8.4
[6] By tangent property,
- 7x – 29 = 2x + 16
- 7x – 2x = 16 + 29
- 5x = 45
- x = 9.
So, WX = 7(9) – 29 = 63 – 29
Answer:
What are you subtracting 25 from?
R = 5n <=== ur expression
lets say there were 10 tickets sold......n = 10
ur revenue (r) would be :
R = 5(10)
R = 50
The equivalent expression of (x+4)² is x²+4x+16.
<h3>What is an expression?</h3>
Expression in mathematics is combination of variables with the use of operations and given rules. It can be in the form of equation, numbers etc.
The given expression is (x+4)².
Simplifying the expression;
(x+4)²
= (x+4) (x+4)
= x²+4x+16
Therefore, the equivalent expression of (x+4)² is x²+4x+16.
