ANSWER
EXPLANATION
The given quadratic trinomial is
Comparing to the general quadratic trinomial:
We have a=1, b=10 and c=-8
The factors of -24 that adds up to 10 are -2 and 12.
We split the middle term to obtain;
Factor;
Factor further;
The last option is correct.
Answer:
D.68ft
Step-by-step explanation:
The common ratio of the sequence is calculated by dividing the second term by the first term or dividing the third term by the second term. That is,
r = 250 / 333 = 0.75
or r = 187 / 250 = 0.748 = 0.75
To get the next term, we multiply 187 by 0.75 giving us an answer of 140.25 or 141.
Answer:
D.3.5
Step-by-step explanation:
4x+2y=10(given)
2x+y=5
y=5-2x-----(1)
y=2x-1------(2)(given)
Since the left side of the equations are the the same,
5-2x=2x-1
4x=6
x=1.5
Sub x=1.5 into eq(1),
y = 5-2(1.5) = 5-3 = 2
so, x+y = 1.5+2 = 3.5
