3a+b
It is the same as: 3*(a+b) or simply 3(a+b)
3*(a + b) or 3a + 3b
3(a + b) + a = 3a + 3b + a = 4a + 3b
3(b5)
3(a+b)+a
It is the same as: 3*(a+b) or simply 3(a+b)
3*(a + b) or 3a + 3b
3(a + b) + a = 3a + 3b + a = 4a + 3b
3(b5)
The algebraic expression is 3(b+5).
3(a+b)+a
(3+b)
The sum of xy times 3 is equal to 3(xy).
the sum of 3 times m and n
5a plus 2b
Algorithm to find the sum and average of 3 numbers: Start. Input three numbers (let's call them A, B, and C). Calculate the sum (Sum = A + B + C). Calculate the average (Average = Sum / 3). Output the sum and average. End. Flowchart: [Start] ↓ [Input A, B, C] ↓ [Sum = A + B + C] ↓ [Average = Sum / 3] ↓ [Output Sum, Average] ↓ [End]
To multiply a number by a sum, you can use the distributive property of multiplication. This states that ( a(b + c) = ab + ac ), meaning you can distribute the number ( a ) across the terms inside the parentheses. For example, if you want to multiply 3 by the sum of 4 and 5, you can calculate it as ( 3(4 + 5) = 3 \times 4 + 3 \times 5 = 12 + 15 = 27 ).
