Question

1. раскройте скобки и упростите: a) 16x + 7(x + 5) б) 14у- 3(8 - у) (2)​

Answer 1

1) 16х + 7(х+5) = 16х + 7х + 35= 23х+35
2) 14у-3(8-у)(2) = 14у-24+3у•2=17у-48

Answer 2

Simplifying Expressions:

a) To simplify the expression 16x + 7(x + 5), we can apply the distributive property. This property states that multiplying a number by a sum is the same as multiplying the number by each term in the sum and then adding the results.

So, we have: 16x + 7(x + 5) = 16x + 7x + 35

Combining like terms, we get: 16x + 7x + 35 = 23x + 35

Therefore, the simplified expression is 23x + 35.

b) To simplify the expression 14у - 3(8 + у) + (2), we can again apply the distributive property.

So, we have: 14у - 3(8 + у) + (2) = 14у - 3 * 8 - 3 * у + 2

Simplifying further, we get: 14у - 24 - 3у + 2 = 11у - 22

Therefore, the simplified expression is 11у - 22.
