Question

5.
The number which is 3 times the sum of z and 5 _____
(a) 3z
(b) 3z + 5
(c) 3(z +5)
(d) None of these​

Answer 1

Answer:

(c) 3(z+5)

Step-by-step explanation:

if z and 5 are added it would be z+5 and this whole is multiplied by 3 so it would be 3(z+5)

Answer 2

Answer:

c) because it is 3 time of sum of (z+5), not only of z or 5

so first we add z and 5 then multiply by 3

so (z+5)×3=3(z+5)

option C
