For A, the scares depend on the hours studying, there is a positive relationship between the two.
Even thought the triangle is reflected, it still maintains the same shape. The two are congruent to each other.
answer: B
The cost of each vegetable is €1.50 per pound
Edward bought 3.25 pounds of carrot.
So the cost of 3.25 pounds of carrots = 3.25 × 1.50 = €4.875
He also purchased
pounds of beet.
Quantity of beet purchased = 6/5 = 1.2 pounds
So the cost of beet shall be = 1.50 × 1.2 = €1.80
He purchased 0.95 pounds of Broccoli
So the cost of Broccoli shall be = 0.95 × 1.50 = €1.425
Total amount spent = 4.875 + 1.80 + 1.425 = €8.10
Edward spent €8.10 on vegetables.
First error is that the legs are a and b so a should be x and b is 6 and c is 10 the second error is at the end they did not take the square root to get x by itself the real answer should be
X^2 +6^2=10^2
X^2+36=100
X^2 =64
X=8
