solution:
One leg of the triangle is given 90ft. the other leg of the triangle is x, and the hypotenuse is given as x+30
According to Pythagoras,
C² = a² + b²
So,
(x +30) = x² + 90²
Use FOIL to expand the binomial:
x² + 60x + 900 = x² + 8100
60x = 7200
X = 7200/60
X = 120
Answer:
The selling price would be Rs 52.5
Step-by-step explanation:
Rs 50 is the actual cost and the 5% profit will amount to Rs 2.5 (50*5%) so total total sales price would be Rs 52.5( Rs 50 + Rs 2.5)
Another way to calculate is (Rs 50 * 1.05) = 52.5
Answer:
The answer for your question is C
Answer:
A = 12a - 24
B = 2x² + 10x
C = 45x - 45
D = 6x² - 3x²
Step-by-step explanation:
You can solve all of these by distributing the first number/variable into the parenthesis. Just multiply the number outside the parenthesis by each of the terms inside the parenthesis.
