(-2a^5b^4) * (42ab^6) = -84a^6b^10
6:13 =83
6+13=19
1 part=83÷19
=4.37
6×4.4=26.4
13×4.4=57.2
26.4:57.2
p.s I got how much money only...
sorry
I believe the answer for the second one is B ( I took this last year but I think it’s that one)
Answer:
x = 31.8
Step-by-step explanation:
From the picture attached,
By applying Pythagoras theorem in right ΔADC,
AC² = AD² + CD²
(22)² = AD² + (16)²
AD² = 484 - 256
AD = √228
= 2√57
Now we apply Pythagoras theorem in right ΔADB,
AB² = AD² + DB²
x² = 228 + (44 - 16)²
x² = 228 + 784
x² = 1012
x = √1012
= 31.81
≈ 31.8
