Tama po yan pa Brainliest naman po please may Explanation po yan pa Brainliest please
Step-by-step explanation:
Explanation No.1
Simplify or Expand
( t + 4 ) × 3
Apply the Distributive Property
The Distribution Property States
For any numbers a,b, and c
a(b+c)=ab+ac
a(b+c)=ab+ac(b+c)a=ba+ca
a(b+c)=ab+ac(b+c)a=ba+caa(b - c)=ab-ac
a(b+c)=ab+ac(b+c)a=ba+caa(b - c)=ab-ac(b - c)a=ba - ca
3t + 3×4
Calculate the product or quotient
3t + 12
Answer : 3t + 12
Explanation No.2
(r + 5) × 3
Apply The Distributive Property
The Distribution Property States
For any numbers a,b,and c
a(b+c)=ab+ac
a(b+c)=ab+ac(b+c)a=ba+ca
a(b+c)=ab+ac(b+c)a=ba+caa(b - c)=ab-ac
a(b+c)=ab+ac(b+c)a=ba+caa(b - c)=ab-ac(b - c)a=ba - ca
3r + 3 × 5
+ 15
Answer : 3r + 15
