Decide whether or not each equation represents a proportional relationship. type yes or no. hint: look at the equation. volume measured in cups (c) vs. the same volume measured in ounces (z): c = 1/8z area of a square (a) vs. the side length of the square (s): a = slatex: ^22 perimeter of an equilateral triangle (p) vs. the side length of the triangle (s): 3s = p length (l) vs. width (w) for a rectangle whose area is 60 square units: l = 60/w

step-by-step explanation:

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.

answer: our required factorization will be

(3x+4)(x²-5)

step-by-step explanation:

since we have given that

now, we will write it as :

so, we get

5(3x+4)

similarly,

here, we get,

2(3x+4)

together it becomes,

hence, our required factorization will be

(3x+4)(x²-5)
