Answer:
Absolute error is 0.05 cm.
Step-by-step explanation:
Given:
Actual length = 12.25 cm
Measured length = 12.2 cm
We need to find Absolute error.
Solution:
Now we can say that;
Absolute error is equal to measured length minus Actual actual.
framing in equation form we get;
Absolute error =
Hence Absolute error is 0.05 cm.
13x - 32
Distributive property: a (b + c) = ab + ac
4 (7x - 2) - 3 (5x + 8) = 28x - 8 - 15x - 24 = 13x - 32
-a^2-a+12
thats the product of (-a + 3)(a + 4)
