Answer:
x = 11
Step-by-step explanation:
2x + 16 = 5x - 17
+ 17 + 17
2x + 33 = 5x
- 2x - 2x
33 + 3x
33/3 = 11
3x/3 = x
Answer:
= r²−4r+3
Step-by-step explanation:
(r - 3) (r - 1)
(r x r) + (r x -1) + (-3 x r) + (-3 x -1)
r² + - r - 3r + 3
= r²−4r+3
Answer:
always a positive number because it represents a distance from the mean.
Step-by-step explanation:
Answer:
B. 3.6 x 10^3
Step-by-step explanation:
(1.2 x 10^-2) x (3 x 10^5)
When we multiply terms with powers , we multiply the factors out front and add the exponents
a * 10^b * c* 10^d = ac * 10^(b+d)
(1.2 x 10^-2) x (3 x 10^5) = (1.2* 3) * 10^(-2+5)
= 3.6 * 10 ^3
