Answer:
(C)
Step-by-step explanation:
In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.
A. , 10 and 116
According to Pythagoras theorem,
⇒
⇒
which does not satisfy the condition, therefore these side lengths do not form a right triangle.
B. 3,6 and 8
According to Pythagoras theorem,
⇒
⇒
⇒
which does not satisfy the condition, therefore these side lengths do not form a right triangle.
C. 30, 40 and 50
According to Pythagoras theorem,
⇒
⇒
⇒
which satisfies the condition, therefore theses side lengths form right triangle.
72 because 63 + 9 is basically 9×8
Dividing the terms: we get
So, Option D is correct.
Step-by-step explanation:
We need to divide the terms:
The division is shown in figure attached.
The quotient is: 2x^2+8x+22
The remainder is: 90
So, Dividing the terms: we get
So, Option D is correct.

Answer:
$3.97
Step-by-step explanation:
Three containers @$2.98 = 3 × 2.98 = $8.94
Less $1 = <u>-1.00
</u>
7.94
Less 50% paid my mom = ½ × 7.94 = <u>-3.97
</u>
Paid by Theresa = $3.97
[(3 × 2.98) - 1] ÷ 2 = (8.94 - 1) ÷ 2 = 7.94 ÷ 2 = 3.97
I think the answer would be 0.025, because (5/8) - (3/5) = 0.025.
