Answer:
2
Step-by-step explanation:
just count the spaces from 0 vertically.
7. X2=25
X=5, x=—5
8. (X—3)2=49
X=10, x=—4
9. X2+3x—28.
X=4, x=—7.
10. 5x2–8=3x.
X=8/5, x=—1
Answer:
5cm+6cm=11cm
Step-by-step explanation:
Adding the two,
Given:
sample population: 1,000
Pop = 30% = 1000 x 30% = 300
Rock = 26% = 1000 x 26% = 260
Country = 20% = 1000 x 20% = 200
1000 - 300 - 260 - 200 = 240
or:
100% - 30% - 26% - 20% = 24%
1000 x 24% = 240
There are 240 people surveyed that do not like any of the top three types of music.
Answer:
28. [A] x² -2x +1 r -16
29. [D] -x² -2x -5 -12/(x-2)
Step-by-step explanation:
In both cases, the answers can be chosen on the basis of the value of the remainder. That value can be found by evaluating the numerator expression at the value of x that makes the denominator zero.
___
28. The root of the denominator is x=-2. The value of the numerator there is ...
(5(-2)³ -6 -15(-2) = -40 -6 +30 = -16 . . . . points to answer choice [A]
__
29. The root of the denominator is x=2. The value of the numerator there is ...
-(2)³ -2 -2 = -8 -2 -2 = -12 . . . . points to answer choice [D]
