Answer:
4 and -6
Step-by-step explanation:
By zero product rule x is 4 and -6.
Hope this helps!
Answer:
x =58
Step-by-step explanation:
The angles are complementary which means they add to 90 degrees
32+ x = 90
Subtract 32 from each side
32+x-32 = 90-32
x =58
The answer choice which represents the group which makes up the best sample for the researcher's survey as described in the task content is; Choice A; Parents of preschool children.
<h3>Which answer choice best represents a sample for the intended survey by Mrs Greenaway's researcher?</h3>
It follows from the task content that; Mrs. Greenaway has decided to open a new preschool in her town.
The need for a researcher therefore arises from the decision to either open the preschool or not.
Consequently, in a bid to choose a sample, Mrs. Greenaway's researcher must make sure the sample chosen is from the population space.
Therefore, answer choice A represents the correct sample.

-4x + 3(2x - 5) = 31 (use distributive property to remove parentheses)
-4x + 6x - 15 = 31 (combine like terms)
2x - 15 = 31 (add 15 to both sides)
+15 +15
2x = 46 (divide both sides by 2)
x = 23
Answer:
b. complementary
Step-by-step explanation:
-Complementary angles are angles that add up to 90°.
-These are usually the two acute angles in the right triangle.
#To verify, lets take the two angles 30° and 60°:
#We can reverse as:
Hence, two angles are said to be complimentary if they sum up to 90°.
