(a-b)(a^2+ab+b^2)/(a-b)(a+b)
Answer:
55°and35°
Step-by-step explanation:
let smaller angle be x
larger angle =x+20
x+x+20=90(Complementary angle)
x= 35
larger number = x+20=35+20=55°
smaller number =x=35°
Answer:
3,864 Km
Step-by-step explanation:
920/60=15.333333
15.33333*252=3,864
Answer:
$(3b+2)
Step-by-step explanation:
The cost of making b bracelets = 4+5b
The cost of making b necklaces = 8b+6.
To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.
Extra Cost = Cost of b Necklaces-Cost of b Bracelets
=(8b+6)-(4+5b)
open the brackets
=8b+6-4-5b
Collect like terms
=8b-5b+6-4
=3b+2
It costs $(3b+2) more to make b necklaces than b bracelets.
Answer:
First evaluate 4^t
put x= 1 in 4^x
It's 4^1 = 4 but f(x) = 8
So we need to multiply with 2
So it's A) 2.4^x
