Which shows two expressions that are equivalent to (–7)(–15)(–5)? (–7)(–75) and (–1)(525) (–1)(525) and (35)(–15) (35)(–15) and (115)(–5) (–1)(525) and (115)(–5)

(-1)(525) and (35)(-15)

Step-by-step explanation:

Here, the given expression is,

(-7)(-15)(-5),

Since, (-7)(-15)(-5) = -525   ( Because, (-) × (-) × (-) = (-) )

First option,

(-7)(-75) and (-1)(525)

= 525 and -525     ( Because, (-) × (-) = (+) and (-) × (+) = (-) )

⇒(-7)(-75)  ≠  (-7)(-15)(-5)

Second option,

(-1)(525) and (35)(-15)

= -525 and -525,

Thus, (-1)(525) =  (35)(-15) = (-7)(-15)(-5)

Third option,

(35)(-15) and (115)(-5)

= -525 and -575

⇒ -575 ≠  (-7)(-15)(-5)

Fourth option,

(-1)(525) and (115)(-5)

= -525 and -575

(115)(-5) ≠  (-7)(-15)(-5)

Hence, (-1)(525) and (35)(-15) are equivalent to the given expression.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
