Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula
Step-by-step explanation:
7p - 4 + 12p = -3(5 + p)
7p - 4 + 12p = -15 - 3p
+ 4 + 4
7p + 12p = -11 - 3p
+ 3p + 3p
22p = -11
p = -1/2 Answer
Answer:
d) 
Step-by-step explanation:
b) 
This expression is not equivalent, as the original expression,
, has 9 multiplied to
instead of y. You can interchange values like this when it comes to addition, but not multiplication.
c) 
This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to
.

d) 
This expression is equivalent, as 9 and
are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:

The answer is 16.3 since
-4.7 is below zero, to get it to zero you would have to add the 4.7 back on. and 11.6+4.7 is equal to 16.3
