Use Pythagorean Theorem of a^2 + b^2 = c^2 where a and b are the legs of the triangle set up by the house height and the ground, and c is the hypotenuse or how long the ladder is. C is going to be our unknown.
Just plugging in you get 25^2 + 35^2 = c^2. Simplify to 625 + 1225 = c^2. Simplify again to 1850 = c^2. The square root both sides to isolate the variable c. C = sqrt(1850) or approximately 43.0116 feet if rounded to 4 decimal places.
The ladder is approximately 43.0116 feet long.
Write the area of the rectangle as a sum: x²＋3x＋2x＋2×3
Write the area of the rectangle as a product: (x＋3)(x＋2)
Write an equation showing each the expressions above are equal: x²＋3x＋2x＋2×3＝(x＋3)(x＋2)
x²＋3x＋2x＋6＝x²＋2x＋3x＋6
This statement is true for any value of x, because both sides are identical.
Hope my answer helped u :)
Will give you the answer but quick question!
how do you put the pic on here?
Answer:
35
Step-by-step explanation:
To calculate the mean(average) of a data set, add all of the numbers together and then divide by the amount of points you have.
Mean = (16+32+41+54+32)/5 because there are 5 numbers you are adding.
