12 less than a number y

Step-by-step explanation:

Example 2: Write each phrase as an algebraic expression.

PhraseExpressionnine increased by a number x9 + xfourteen decreased by a number p14 - pseven less than a number tt - 7the product of 9 and a number n9 · n   or   9nthirty-two divided by a number y32 ÷ y   or   

In Example 2, each algebraic expression consisted of one number, one operation and one variable. Let's look at an example in which the expression consists of more than one number and/or operation.

ou would have 12 of each

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
