Answer:
1. 24
2. B
Step-by-step explanation:
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
Answer:
C. 3
Step-by-step explanation:
2x+6
Divide 2 on both sides
x=3
From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :
