Answer:
The equation for area of a triangle is height multiplied by the base length, divided by 2. So, if the height is 2, and the base is 4, then you multiply the two together, making 8, and then divide it by 2, making the final area 4. So if the dimensions are doubled, then the equation would be 4 times 8 divided by 2. Which is 16. If we do this again with 16 times 8, we will get 128, which when divided by two is 64. This is 4 times 16, just as 16 is 4 times the original answer 4. This means that every time you double the dimensions you will get the original answer multiplied by 4.

Answer:
134.4 centimeters
Step-by-step explanation:
This question is asking us for a missing leg on the triangle, lets call it x. Using the Pythagorean theorem (a²+b²=c²), we can figure out what value is missing (either a or b, they are interchangeable).
replace the values in the equation.
83²+x²=158²
get rid of the exponents.
6,889+ x² = 24,964.
subtract 6,889 from 24,964.
x²=18,075.
find the square root on both sides of the equation.
x=134.4432966.
I am assuming you want this rounded to the nearest tenth.
134.4 is your answer.

Answer:
-12x + 12 = 32............................. the equation
Step-by-step explanation:
to determine the equation in this 12(1-x) = 36 expression is quite simple, you only need to open the bracket .
solution
12(1-x) = 36
12 - 12x = 32
-12x + 12 = 32............................. the equation
we can further evaluate for the value of x
-12x = 32 - 12
-12x = 20
divide both sides by the coefficient of x which is -12
-12x = 20
-12x/-12 = 20/-12
x = -1.67
