The answer is 36 what is the make 10 strategy
Assoli18 [71]2 years ago

Answer:

If we add two numbers or more than two numbers then make ten strategy is a   basic strategy to learn addition .

In this strategy we break the smaller number in terms to make the larger number equals to ten or tens .

For example :-  

8+7=8+(2+5)=8+2+5=10+5=15

Now, the given addition problem is 9+27

Here we break 9 to make 27 equals to 30 or 3 tens.

We can write, 9=6+3

Such that 9+27=(6+3)+27=6+3+27=6+(3+27)=6+30=36

hence, 9+27=36

The answer should be 6! all you have to do is plug the numbers into the equation!
it would be like this:
-1^2+3^2+(-1)-3
doing all of that would equal 6!

HELP! ASAP!

Step-by-step explanation:

Part A:

So the height is going to be x when you fold the sides up. So that's one part of the volume but for the width it was going to be 4 but since two corners were cut out with the length x the new width is going to be (4-2x). The same thing applies for the length which should be 8 inches but since two corners were removed with the length x it's now (8-2x)

v = x(4-2x)(8-2x)

Part B:

The volume can be graphed although there must be a domain restriction since the height, width, or length cannot be negative. So let's look at each part of the equation

so for the x in front it must be greater than 0 to make sense

for the (4-2x), the x must be less than 2 or else the width is  negative.

for the (8-2x) the x must be less than 4 or else the length is negative

so the domain is going to be restricted to 0 < x < 2 so all the dimensions are greater than 0

By using a graphing calculator you can see the maximum of the given equation with the domain restrictions is 0.845 which gives a volume of 12.317
