What is the quadratic equation that has roots of ,-3 And 2/5​
prohojiy [21]

Answer: 5x² + 13x - 6 = 0

Step-by-step explanation:

Represent the roots with X i.e.

X = -3 ; X = 2/5

Moving the values of X over the equator we have;

X + 3 = 0 ; 5X - 2 = 0

Equating both equations to zero we can obtain;

(X + 3)(5X - 2) = 0

Opening the brackets we get;

5x² - 2x + 15x - 6 = 0

The  result of the above equation gives;

5x² + 13x - 6 = 0

Mirror and the three friends each had three over for food of they need it to have 5 feet of rope altogether. Do they have enough
BabaBlast [244]

Answer:

Do they have enough?

Nope, they don't have enough.

Step-by-step explanation:

They would not have enough because 3/4 times 4 would not equal 5...it would equal 3. Mario and his 3 friends each have 3/4 foot of rope. They needed 5 feet of rope altogether. Do they have enough rope? They would need 2 more feet of rope to complete the 5 feet. But they do not have enough feet of rope to make 5 feet.

Hope it helped u if yes mark me BRAINLIEST!

Tysm!
