(2x + 3y)4
Distribute
4*2x = 8x
4*3y = 12y
8x + 12y
Answer: 8x + 12y
We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0
As zero is in the denominator, it can't be defined.
In short, Your Answer would be: "False"
Hope this helps!
Answer:
210 Km
Step-by-step explanation:
Distance travelled is calculated as
distance = speed × time ( time is in hours )
= 90 × 2 
= 90 × 
= 30 × 7
= 210 Km
Answer:a=3/4
b=3/4
Step-by-step explanation:
3a+5b=6
9a+7b=12
-3(3a+5b)=-3(6)
9a+7b=12
-9a-15b=-18
9a+7b=12
-8b=-6
b=3/4
3a+5(3/4)=6
3a+15/4=6
3a=9/4
a=3/4
2x+6=1
-5+6=1
-5÷2=-2.5
x=-2.5
