Answer: no
Step-by-step explanation:
no. one is the fraction 1 / 3 and the other is the fraction 3 / 1
Perpendicular slopes multiply to -1, so are <em>negative reciprocals.</em>
-1 / -3 = 1/3
Answer: B. 1/3
Answer:
Step-by-step explanation:
2 / 3 ( 4x + 9 )
Distributive property
2 / 12x + 27
PEMDAS
-6-4(3x2)+5^2
-6-4(6)+5^2
distribute
-6-24+5^2
-6-24+25= -5
Answer:
15/4 in or 3.75 in
Step-by-step explanation:
Find your equations:
L = 4w + 9 in
A = L*w = 90 in^2
Substitute L:
L*w = 90 in^2 <-- L = 4w + 9
(4w + 9in)w = 90 in^2
4w^2 in^2 + 9w in = 90in^2
Solve Simultaneously:
w = -6 in, 15/4 in
Width is positive so it is 15/4 in or 3.75 in.
Double check:
(4w + 9in)w = 90 in^2
(4*3.75in + 9in)(3.75in) = 90 in^2
