If (h + h) · (h. h) = 16, find the value of h. — HELP ME PLEASEEEE

Answer:

h = 2

Step-by-step explanation:

I'm assuming your periods are multiplication signs.

(h + h) X (h X h) = 16

When adding two variables like the first set of parentheses, it would become 2h.  When multiplying two like variables, you add the exponents.  h is the same as writing h¹.  So h¹ x h¹   gives you the answer of h².

So now your equation would look like:

2h  X  h²  = 16

As above, when you multiply two like variables you would add the exponents.  Also if any number are in front of the variable you would multiply those numbers.  So you have 2h¹ x 1h² and that would be 2h³.  If it had been

2h¹ x 2h², your answer would have been 4h³.

But so far you have 2h¹ x 1h² = 16

2h³ = 16

Dividing both sides by 2 you get

h³ = 8

To find h you have to take the cubed root of 8.  What number multiplied by itself 3 times gives you 8?    2 x 2 x 2 = 8     2 x 2 = 4 and x 2 = 8.

h = 2

If you put this into the original equation you have:

(2 + 2) x ( 2 x 2) = 16

 ( 4 ) x ( 4 ) = 16

A rectangle has an area (x2-17x+72) square units.Since the area of a rectangle is determined using the formula, A= lw, what coul
hammer [34]
Geez this is a doozy

okay first factor the binomial using binomial theorem. you probably don't remember that (at least I didn't) so here it is.

{x}^{2}  - 17x + 72
you have to figure out what two numbers add to -17 and multiply together to make 72

so make a table of all the numbers that add to 17 then multiply them together and see of they make 72. since it's -17 we will need to use two negative numbers:

-1 * -16 = 16
-2 * -15 = 30
-3 * -14 = 42? idk
-4 * -13 = something, math is hard
keep going until...
-8 * -9 = 72

so it's -8 and -9 are the factors we want.
we wrote this as:

(x - 8)(x - 9)
seeing this equal as our area in the a=l*w formula gives:

(x - 8)(x - 9) = l \times w
Now, plug in a number greater than 9.
It has to be greater than 9 because anything less than that would give us a negative area. Let's use 10 because it's easy. It doesn't matter which number you use as long as it's greater than 10. The problem appears to say it just wants a possible length and width, not a specific answer.

(10 - 8)(10 - 9) = lw
2 = lw
so factors of 2.
length could be 1 and width could be 2 or vice versa.

you could also choose a different number than 10. let's try 20.

(14 - 8)(14 - 9) = lw
(6)(5) = lw
30 = lw
so lw could also be 10 and 3 in this case. or 5 and 6. or 1 and 30. all these answers would be correct.
