A=12h(a+b) Solve for h.

nikklg [1K]

Answer:

$h=\frac{A}{12a+12b}$

Step-by-step explanation:

Solve for h, means that you have <em>to clear</em> h.

We have the expression $A=12h(a+b)$

We can divide both sides of the equation in (a+b):

$A=12h(a+b)\\\frac{A}{(a+b)}=\frac{12h(a+b)}{(a+b)}\\\\\frac{A}{(a+b)}=12h$

Now divide again both sides of the equation in 12.

$\frac{A}{(a+b)}=12h\\\\\frac{A}{12(a+b)} =\frac{12h}{12}\\\\\frac{A}{12a+12b} =h$

Observation: Distributive property: $c(a+b)=ca+cb$ , then: $12(a+b)=12a+12b$

The answer is: $h=\frac{A}{12a+12b}$

A triangle has two sides of lengths 7 and 9.what value could the length of the third side be?

Diano4ka-milaya [45]

The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.

So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.

285y = 15 what’s the solution

lions [1.4K]

Answer:

$285y = 15\\y = \frac{15}{285}\\y = \frac{1}{19}$

Step-by-step explanation:

You have to divide the entire equation by 285 to get y alone.

Then, simplify the fraction to get 1/19.

105,159 rounded to the nearest ten thousand

IceJOKER [234]

If you look at the hundereds place you see it is under the number 5 which means you would drop 1, 5, & 9 and the answer would be 105,000. If the number was above 5 you would have had to make it 106,000.
