Pythagorean Theorem<h2>
Verbally:</h2>
Let's say a and b are the legs, and c is the hypotenuse. Then, algebraically, the theorem is,
Answer:
f(-4) = 9
Step-by-step explanation:
To find which expression to use, see which one x = -4 fits in. That is <em>x² - 5</em>, since -4 < 3.
Then, plug in the number: (-4)² - 5
Square: 16 - 5
Subtract: 9
f(-4) = 9
Answer:
6cm ; 22cm
Step-by-step explanation:
Given that:
Total Length, AD = 28cm
AB =x cm
BC = (x +5)cm
CD = 2x - 1 cm
4x + 4 = 28
4x = 28 - 4
4x = 24
x = 24 / 4
x = 6cm
The length of BD
BD = BC + CD
BD = (x + 5) + (2x - 1)
x = 6
BD = (6 + 5) + (2(6) - 1)
BD = 11 + (12 - 1)
BD = 11 + 11
BD = 22 cm
So that answer is in this picture that I wrote on my white board, count all of the hundreds I drew on the board.
