Answer:
<em>b = 12 cm</em>
Step-by-step explanation:
<u>The Pythagora's Theorem</u>
The area of a square of side length x is
We have three squares, two of which have side lengths of a=5 cm and b= 13 cm.
The combined area of the smaller squares is the same as the area of the largest square. We cannot say at first sight which square is the largest, we'll assume the square of side length of 13 cm is the largest one. Thus:
Where b is the unknown side length.
The above expression corresponds to the Pythagora's Theorem formula. Solving for b:
b = 12 cm
Answer:
E. 5
Step-by-step explanation:
Let's rewrite the equation in the form of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
2x + y = 5
y = -2x+5
M, the slope, is -2
<u>5, b, is the y-intercept</u>

Answer:-8
Step-by-step explanation: you add -1+ -1, to get -2, then -2+-2, to get -4 and so forth.
Answer:
28
Step-by-step explanation:
First multiply 8 by 4 to get 32. Now there is a small triangle in the bottom. Multiply 4 by 2 to get 8. Then divide 8 by 2 to get 4, the area of the triangle. Now lastly 32-4 to get 28 square units, the area.
Answer:
11/4
Step-by-step explanation:
2 times 4 equals 8 and plus 3 equals 11 and dem is 4 so 11/4
