I got an answer of 77, so I am assuming it may be the closest option of 74?
Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
<span>If water and oil are combined in a container, the resulting liquid is a suspension. Water and oil do not mix. They form a heterogeneous mixture (a mixture whose composition is not uniform). The kind of heterogeous mixture that water and oil form is a suspension because the two lquids separate and can be easily distinguished. An emulsion, is an heterogenous mixture where small drops of one of the liquids disperse into the other liquid, so they form a stable mixture that will not separate quickly. Mayonaisse is an example of emulsion, because it consists of two liquids (oil an eggs) dispersed one into the other. Milk is also a emulsion of fat and water. So the specif term for the liquid resulting from water and liquid combined in a container is the option A. suspension.</span>
