25A2B is a 5-digit number. If the number is divisible by 5 and 9, find all the possible values of A and B. Explain also.
3241004551 [841]

Answer:

25020, 25920, 25425

Step-by-step explanation:

To find if our number is divisible by 5 the number must end with 0 or 5, divisibility by 9 is if sum of all numbers in number is divisible by 9,

We know B must end with 0 or 5

1. Case 25A20 sum of that number is 9 so if we pick 0 as A we have first number because 9/9=1

We can put A as 9 because 18/9=2

2. Case B = 0, sum is 14 so we need pick A as 4 to get 18.

Y=-4(x-2)2+4<br> what is the x intercept
valentina_108 [34]
<h2>Solving for the x-intercepts of a Parabola given the Equation</h2><h3>Answer:</h3>

x = 3 and x = 1

<h3>Step-by-step explanation:</h3>

x-intercepts are just the values x when y = 0.

Solving for x:

0 = -4(x -2)^2 +4 \\ -4(x -2)^2 +4 = 0 \\ -4(x -2)^2 = -4 \\ 4(x -2)^2 = 4 \\ (x-2)^2 = \frac{4}{4} \\ (x -2)^2 = 1 \\ x-2 = \pm \sqrt1 \\ x -2 = \pm 1 \\ x = \pm 1 +2

Solving for the Positive Square Root:

x = 1 +2 \\ x = 3

Solving for the Negative Square Root:

x = -1 +2 \\ x = 1

Find the area. Simplify your answer.
Shalnov [3]

9514 1404 393

Answer:

  x^2 +8x +12

Step-by-step explanation:

The area is the product of length and width. The product can be simplified using the distributive property.

  A = LW

  A = (x +6)(x +2) = x(x +2) +6(x +2)

  A = x^2 +2x +6x +12

  A = x^2 +8x +12

<h2>Answer:</h2><h2></h2>

$3,250

$115 x   ×  = $2600

23 Meals.

<h2></h2><h2>Step-by-step explanation:</h2><h2></h2>

Simply take 115 and multiply it by 50, giving you 5,750, and subtract 2,500, leaving us with 3,250 ( add dollar symbol ).

For the second problem, we go like this: $115 x   ×  = $2600 all we need to do is find the value of × So we divide 2600 by 115, which gives us 22.608 ( round up to 23 ) so × = 23
