Answer:
A. 5
Step-by-step explanation:
The longest side of the right triangle is the hypotenuse and it is √61 units. The other legs of the triangle is x unit and (x + 1) units.
From Pythagoras theorem for right angle triangle, the square of the hypotenuse is equal to the sum of the square of the other sides of the triangle. This implies that:
(√61)² = (x)² + (x + 1)²
x² + x² + 2x + 1 = 61
2x² + 2x + 1 - 61 = 0
2x² + 2x -60 = 0
Dividing through by 2 gives:
x² + x - 30 = 0
x² + 6x - 5x - 30 = 0
x(x + 6) -5(x + 6) = 0
(x-5)(x+6) = 0
x-5 = 0 or x+6 = 0
x = 5 or x = -6
Since the length of a side cannot be negative, x = 5 units
Answer:
10.50$
Step-by-step explanation:
We know that the price for 12 cans is $18. So we can set up an equation. Let c equal the price of one can. One can cost 1.50 thats cause 18 divided by 12 is 1.50. Now you just take 1.50 and add that 7 times.
Answer:
Nope.
Step-by-step explanation:
area square: s^2 if one side is 2 cm: are ais 4 cm
rhombus square: (big diagonalxsmall diagonal)/2
what counts on the rombus is not the side, but the diagonals. The diagonals are usually longer than the side of the square, so the area of the rombus is bigger.
