For the first one x must not = -3 because that would make the denominator zero.
second question This simplifies to u / (u+2)
Answer:
2+348)(27252)
Step-by-step explanation:
It is this because it’s da right answer
13.
1st: split the 1 shape into 2 shapes. (spit across to where you see one right angle(top), and a trapezoid(bottom)
2nd: now what i did was fill that gap to where the total height is 9 and the total length is 7. ( if you don't want to do that it is fine )
3rd: for the top do 5 times 2 = 10
4th: for the bottom do 4 times 5 = 20
5th: add 10 (top) and 20 (bottom) = 30
You got the method and answer correct in this question, congrats!
Less = subtract
than =switch the order
product = multiply so
5 x -4 - 8
= -20 - 8
= -28
