$\\ \sf\longmapsto 2x^2+3x^2+3(-1)=5x.x+5x.1$

$\\ \sf\longmapsto 5x^2-3=5x^2+5x$

$\\ \sf\longmapsto 5x^2-5x^2-3=5x$

$\\ \sf\longmapsto 5x=-3$

$\\ \sf\longmapsto x=\dfrac{-3}{5}$

The first number is equal to 4 times the second number, the difference of the number is 12, what are the two numbers?

Irina18 [472]

let 1st and 2nd no be x and y respectively

1st case:x=4y

2nd case:x-y=12

substituting the value of x in 2nd case

4y-y=12

3y=12

y=12÷3

y=4

now putting the value of y in 1st case

x=4×4

=16

Ginny's house is 20 yards long. She says that the house is 720 feet long. Is Ginny correct

SpyIntel [72]

1 yard= 3 feet
_yard=720 feet
720 divide 3= 240
So it should be 240 yard
So it is incorrect
