What number should be added to both sides of the equation to complete the square? x^2-40x=0

Answers

Answer:

+40

Step-by-step explanation:

Answer:

400

Step-by-step explanation:

When completing the square, all you need to do is take half the coefficient of x, and square it.

In this case the coefficient of x is -40, and half of that is -20.  -20 squared is 400, and that is what you need to add to both sides.

Note that when completing the square, you'll always be adding a positive number unless coefficient you're working with is an imaginary or complex number.

Answer:

b = 21 ft is the answer.

Step-by-step explanation:

a = 28 ft

b = ?

c = 35 ft

According to the Pythagoras theorem,

a² + b² = c²

28² + b² = 35²

784 + b² = 1225

b² = 1225 - 784

b² = 441

b = 21 ft

∴ b = 21 ft is the length of the missing leg.

in how many ways can 4 mangoes and 3 apples be distributed among 7 children if each child receives only 2 fruit?​

Answers

solution

this is what I did. total number of ways without any restriction =900. we have to subtract the case when at least one child doesn't get any fruit. let that be C1∪C2∪C3 and we use the principle of mutual inclusion and exclusion to find that. C1∪C2∪C3=C1+C2+C3−(all two intersections)+3 intersections (no one gets a fruit case) =3⋅60−3+1=178 so case where each child gets at least one fruit =900−178=722.
