Answer :
Answer:
4 × 3 - 2 × 5 = 12 - 10 = 2
2x² + 3y² = 2 × 9 + 3 × 25 = 18 + 75 = 93
Substitute the values for the variables. Since we are given that x=3 and y=5, the new equations will be 4(3)-2(5) and 2(3)^2+ 3(5)^2.
4•3=12
2•5=10
12-10= 2.
Therefore, 4(3)-2(5)=2.
3•3=9
9•2=18
5•5=25
25•3=75.
75+18=93
So, 2(3)^2+ 3(5)^2=93.
The answers will be 2 and 93
4•3=12
2•5=10
12-10= 2.
Therefore, 4(3)-2(5)=2.
3•3=9
9•2=18
5•5=25
25•3=75.
75+18=93
So, 2(3)^2+ 3(5)^2=93.
The answers will be 2 and 93
