Joe makes belts. He has 9 buckles. He uses 12 rivets on each of 4 belts and 15 rivets on each of 2 belts. He has 22 rivets left
Lerok [7]

Answers:

1. There are rivets on the belts.

2. Extra information given in the problem:

a. He has 9 buckles.

b. He has 22 rivets left over.


Solution:

1. Total rivets on the belts=(12 rivets/belt)(4 belts)+(15 rivets/belt)(2 belts)

Total rivets on the belts=48 rivets+30 rivets

Total rivets on the belts=78 rivets


2. The extra information given in the problem is the information that we didn't use to solve it. In this case:

a. He has 9 buckles.

b. He has 22 rivets left over.

How can undefinable terms be used to create precise mathematical definitions?
chubhunter [2.5K]

Answer:

This is done by stating descriptions of these terms.

Step-by-step explanation:

Undefinable terms are terms with no formal definitions. Formal definitions are obtained when specific words are used to define a term. In mathematics, specifically, Geometry words like line, point, and plane have no definite definition, So descriptions are used to identify them.

For example, in describing a point, we note that a point has no dimensions, it is usually denoted with a capital letter, and it indicates a position. Also in a coordinate plane, it is denoted with descriptions such as  (u,v). Corresponding descriptions are given of other undefinable terms.

Factor each of the following expressions. What similarities do you notice between the examples in the left column and those on t
Bumek [7]

Answer:

(a) (x+1)(x-1)

(b)(3x+1)(3x-1)

(c) (x+3)(x+5)

(d)(2x+5)(2x+3)

(e)(x+y)(x-y)

(f) (x^{2}  +y^{2})(x+y)(x-y)

Step-by-step explanation:

We have to factorize the following expressions:

(a) x²-1 =(x+1)(x-1) (Answer) {Since we know the formula (a²-b²) =(a+b)(a-b)}

(b) 9x²-1 =(3x+1)(3x-1) (Answer) {Since we know the formula (a²-b²) =(a+b)(a-b)}

(c) x²+8x+15 = x² +3x+5x+15 =(x+3)(x+5) (Answer)

(d) 4x²+16x+15 =4x²+10x+6x+15 = 2x(2x+5) +3(2x+5) =(2x+5)(2x+3) (Answer)

(e) x²-y² =(x+y)(x-y) (Answer)

(f) x^{4}-y^{4} =(x^{2}   +y^{2})(x^{2}  -y^{2})=(x^{2}  +y^{2})(x+y)(x-y) (Answer) {Since we know the formula (a²-b²) =(a+b)(a-b)}
