formula for Surface Area = 2(LW + WH + HL)
- putting the known values,
Surface Area = 2(8×10 + 10×10 + 10×8) m²
<u>Surface</u><u> Area</u><u> </u><u>=</u><u> </u><u>2</u><u>(</u><u>2</u><u>6</u><u>0</u><u>)</u><u> </u><u>m²</u>
<u>Surface</u><u> Area</u><u> </u><u>=</u><u> </u><u>5</u><u>2</u><u>0</u><u>m</u><u>²</u><u> </u><u>(</u><u> </u><u>Option</u><u> </u><u>C</u><u>)</u>
<span>i think you mean discriminant in part A
</span>
Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
Answer:
8,110
Step-by-step explanation:
It's falling by 90 each time
Y = 3x + 5
(0,5) (1,8)
y = -2x + 20
(0,20) (1,18)
