For #1 you're just plugging in the numbers that are in the parentheses for x.

For example:
f(2)
Take the given equation to plug in for x:

x^2-4x+5

(2)^2-4(2)+5

And from there you get the answer. Your final answer will look like this:

f(2)=? {the answer you got when you plugged in}

Which is the length of the hypotenuse of the triangle?

Pepsi [2]

Since this is a right triangle, we can use the Pythagorean Theorem, which states a² + b² = c² in a right triangle.

Plugging our numbers in, we get:

(12)² + (35)² = c²

From there, we can square the numbers.

(144) + (1225) = c²

Then, we can add them together to find the sum;

(1369) = c²

And finally, we can find the square root of both sides.

(37) = c

Therefore, 37 is the answer and your answer choice is correct.

The triangle below has a total perimeter of 450 cm:

Korvikt [17]

Equation: 450 = 128 + 150 + n

work:

1st step:
128+150 = 278

2nd step:
450-278 = 172

answer: 172

3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450
