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

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

Step-by-step explanation:
four Point perspective
Answer:
one point perspective
Step-by-step explanation:
It is one point perspective because if you are thinking about birds eye view, you have to consider that they height a bird can fly is very very high. So you have to be thinking critically, it cannot be 4 point perspective nor 3 point perspective due to the fact, that that is worm eye view. Thus, the answer it leaves you with is 1 point view and 2 point perspective. Two point perspective is us, it would be like us watching a building (which isn't that high). Hence, the last answer you are left with is one point perspective.
For reference you can look at the picture:

3/12+4/12
7/12
The whole pizza is gonna be 1 since a whole pizza
1-7/12
that would be 5/12
Answer:
5/12
Step-by-step explanation:
1/4 + 1/3 + x = 1
7/12 + x = 1
7/12 - 7/12 + x = 1 - 7/12
x = 5/12

Step-by-step explanation:
Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers.
If there are 2.54 centimeters in one inch, how many square centimeters are in one square inch? Hint: It is not 2.54! How is determining this conversion ratio related to linear and area scale factors for similar shapes?
Answer: It is related because linear scale factors are also squared for area scale factors.
Step-by-step explanation: Imagine two squares, which are similar (all squares are similar), and one has a side length of two and other has a side length of four. The length ratio is 1:2. But if you calculate the areas the area ratio is 1:4, which is the linear scale factor of two squared to get to 4
