Question

5 (4a+2b)+2 (7a+12b)​

Answer 1

5(4a+2b)+2(7a+12b)=20a+10b+14a+24b=34a+34b = 34(a+b)

Answer 2

5 (4п+2b) + 2 (7a+12b)

20a+10b+14a+24b

34a+10b+24b

34a=34a

Answer 3

To simplify the given expression, follow the order of operations (PEMDAS):

1. P - Parentheses
2. E - Exponents
3. MD - Multiplication and Division (from left to right)
4. AS - Addition and Subtraction (from left to right)

Given expression: 5(4a + 2b) + 2(7a + 12b)

Step 1: Distribute the multiplication (using the distributive property)

5 * 4a = 20a 5 * 2b = 10b 2 * 7a = 14a 2 * 12b = 24b

Expression after distributing the multiplication: 20a + 10b + 14a + 24b

Step 2: Combine like terms (terms with the same variables)

(20a + 14a) = 34a (10b + 24b) = 34b

Expression after combining like terms: 34a + 34b

The simplified expression is: 34a + 34b
