Answer:
90
Step-by-step explanation:
Answer:
c = 
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
c² = 9² + 6² = 81 + 36 = 117 ( take the square root of both sides )
c =
≈ 10.8 ( to 1 dec. place )
The first one is 61
180-119=61
Answer:
7 1/2 inches
Step-by-step explanation:
3 × 2 1/2 = (3×2) +(3×1/2) = 6 + 3/2 = 6 + 1 1/2 = 7 1/2
The stretched clay would be 7 1/2 inches long.
<span>8(3m+5)=2m-4
Multiply the number outside of the parenthesis with the numbers inside the parenthesis
24m+40=2m-4
Subtract 2m from both sides so that the variable is only on one side
22m+40=-4
Subtract 40 from both sides
22m=-44
Divide 22 on both sides
Final Answer: m= -2</span>
