The value of (7²-√81) + √125) is 45
What are square root and square?Squares are the numbers, generated after multiplying a value by itself. Whereas square root of a number is value which on getting multiplied by itself gives the original value. Hence, both are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2.Similarly, the square of 4 is 16 and the square root of 16 is 4.
A perfect square is a number, from a given number system, that can be expressed as the square of a number from the same number system. Therefore 4, 16, 25 are examples of perfect squares
7²-√81) + √125 is calculated as
49- 9+ 5 = 45
Therefore the value of 7²-√81) + √125 = 45

x varies directly with
y. If x = 60 when
y = 75. find x when
y = 32.
Answer:
x=17
Step-by-step explanation:
Answer:
25.6
Step-by-step explanation:
find constant of variation ('k'):
y = kx
75 = 60k
k = 75/60 or 5/4
32 = 5/4x
cross-multiply:
5x = 128
x = 25.6

Can someone please help me will give brainlist
Answer:
yes
Step-by-step explanation:
start by solving for the missing value. all angles of a triangle should add up to 180. Subtract 31 adn 106 from 180 from the left side, you will get 43. Now do the same to the other side. 180 subtracted by 31 and 43 make 106. Thus, making the triangles the same. hope this helps
