Sry I'm couldn't solve the second one but the ans for the 1st is 504 sq units
(-4,-3) need 20 characters
Answer:
find f(5) and g(5) then divide f(5) by g(5) i.e f(5)/g(5) Answer will be 25/6
Step-by-step explanation:
your don't see what went wrong ?
Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is
-2x - 3
Answer
Find out the how long are the two line segments together answer in cm .
To prove
As given
i am measurng two line segments the first line is 30centimeter long.
The second line segment is 500 millimeter .
As
1 millimeter = 0.1 centimeter
Now convert 500 millimeter into centimeter .
500 millimeter = 500 × 0.1 centimeter
= 50 centimeter
Thus second line segment be 50 centimeter long .
Total length of two line segments = 30 + 50
= 80 cm
Therefore the 80 cm long are the two line segments together answer in cm .
