Question

if x =3 ,y = -2 and z = 5 find the value of the follwing 5xy + 4yz -3xz.

Answer 1

hello friend!
here is your Answer

X = 3
y =-2
z = 5

so putting all the value in equation

5× 3×-2 + 4× -2×5 -3× 3×5

=> -30-40-45
=> -115 Ans

Answer 2

Answer:

5xy+4yz−3xz

x=3, y=−2, z=5

⇒5(3)(−2)+4(−2)(5)−3(3)5

⇒−30−40−45=−70−45=−115.

I hope this answer will help you
