Answer:
uhm idk..... it's 4 quarters, or 100 pennies, or 10 dimes, or 20 nickels
i don't know what ur asking sorryyyy
Step-by-step explanation:
1)
2)
∠ABC=90°
if ∠DAB =110 then ∠BAC =180-110 =70° because straighht lines make 180°∠s
use the fact that the sum of angles in a Δ is 180°
∠ABC= 180-20-70= 90
an = a1 +d(n-1)
a4 =a1+d(4-1)
-4 = -1+d(3)
add 1 to each side
-3 = 3d
d= -1
an = -1 +-1 (n-1)
an = -1 -n +1
an = -n
Choice D
24x^9*z^5
combine coefficients and add exponents for like terms
hope this helps you :)
