Amit solved the equation 5/12 = -x/420 for x using the steps shown below. What is Amit's error? 5/12 = -x/420
5/12(420) = -x/420(420)
x = 175

A: Amit should have multiplied both sides by 5/12
B: Amit should have multiplied both sides by 12/5
C: The product of 5/12 and 420 is not equal to 175
D: The product of 5/12 and -420 should have been the value of x

what is the question here

step-by-step explanation:

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
