Answer:
A=20,000 m2 per year
Step-by-step explanation:
we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m
V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2
2(7n-3)=-n+114
14n-6=-n+114
15n=120
n=8
check...
2(7*8-3)=-8+114
2(56-3)=106
2(53)=106
106=106
Answer:
see explanation
Step-by-step explanation:
To find the roots factor the left side
x³ + 7x² + 12x = 0 ← factor out x from each term
x(x² + 7x + 12) = 0
x(x + 3)(x + 4) = 0
Equate each factor to zero and solve for x
x = 0
x + 3 = 0 ⇒ x = - 3
x + 4 = 0 ⇒ x = - 4
Roots are x = - 4, x = - 3, x = 0
Answer: 544 cm²
<u>Step-by-step explanation:</u>
There are 5 sections to the tent:
- Front (triangle): A =
· b · h - Back (triangle): same dimensions as Front
- Base (rectangle): A = L · w
- Left Side (Rectangle): A = L · w
- Right side (rectangle): same dimensions as Left Side
Total Surface Area = Front & Back + Base + Sides
= 2[(12 · 8)] + (12 · 14) + 2(14 · 10)
= 96 + 168 + 280
= 544
Answer:4x -9 >= -21
4x >= -12
x >= -12/4
x >= -3
so this number line started with -3 and go away till + infinity
hope this will help you
