Answer:
30
Step-by-step explanation:
Find the trapezoid area.
A=1/2h(b1+b2)
A=1/2(12)(6+15)
A=1/2(12)(21)
A=6(21)
A=126
Find the square
A=s²
A=15²
a=225
Add them.
126+225=351
Divide
351÷12=29.25
Round to 30 because 29 not enough.
30 with extra
It would be 29 and a little more but she would need 30 and have leftovers.
0.29
7x=2
/7 /7
x=0.29
-hope it helps
The 2 answers are t = 0.5 Seconds and t= 1.5 seconds
(0 - (9 • (a^666))) - (22•3ab^6)
(0 - 32a^666) - (22•3ab^6)
-12ab^6 - 9a^666 = -3a • (4b^6 + 3a^665)
Final result :
-3a • (4b^6 + 3a^665)
