Steps:
1st write out equation
Second write the conjugant and multiply it.
After multiplying you should get,
now after simplifying you should get
In this equation x=-1/15 or negative one fiftenth.
I'd suggest rounding up both $13.59 and $1.85: $14 and $2. Subtracting the discount (~$2) from the price (~$14) results in $12. Subtracting this discounted price from the $20 cash in hand results in change of approx. $8.
Step-by-step explanation:
In the given figure, its a cube with edge 7.7 inches.
Surface area = 6a²
Where ‘a’ denotes the edge
→ 6(7.7)²
→ 6 × 59.29
→ 355.74
Rounding nearest tenth :
→ 355.8
Answer:
w =
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
w² + 7² = 14²
w² + 49 = 196 ( subtract 49 from both sides )
w² = 147 ( take the square root of both sides )
w =
