Answer:
47
Step-by-step explanation:
32+[4×(15÷3)]−5
At first we have to apply "BODMAS" rule. According to the rule, we will work 1st bracket.
Hence,
32+[4×5]−5
Then, we will take 3rd bracket into consideration,
32+20−5
Then, we will use addition from the BODMAS rule-
52 - 5
Finally, subtracting 5 from 52, we can get
= 47
The value of the expression is 47.
The leg is 8 cm long
An isosceles right triangle has the length of its hypotenuse and opposite equal
Let us call the length x
From Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides
Thus, we have ;
x^2 + x^2 = (8 √2)^2
2x^2 = 128
x^2 = 128/2
x^2 = 64
x= √64
x = 8 cm
