Answer:
? = 16
Step-by-step explanation:
x2 - 8x + ? = 42 + ?
1. Take the coefficient of the middle term 8x, which is 8 and divide it by 2. . Then square it
2. Take 16 and add it to both sides:
2. Take half of the coefficient 8 that you divided by 2, which is 4 and insert 4 into the equation
3. ? = 16
Step-by-step explanation:
We need to find the height of the triangle first.
Height=>sin(60°)=h/3 but sin(60°)=√3/2
h=3×√3/2=3√3/2
Area=½×base×height
A=½×3×3√3/2
A=9√3/4
Answer is option A
Answer:
0.55M + 22.65
Step-by-step explanation:
Well, c is equal to s + i, and s is .45m + 17.75, i is .15m + 4.9
add them to get
0.55m + 22.65
