Answer:
184 cm²
Step-by-step explanation:
Surface area of the rectangular box is expressed as S = 2(LW+LH+WH)
L is the length of the box = 90 cm
W is the width of the box = 50 cm
H is the height of the box= 90 cm
If there are error of at most 0.2 cm in each measurement, then the total surface area using differential estimate will be expressed as shown;
S = 2{(LdW+WdL) + (LdH+HdL) + (WdH+HdW)
Note that dL = dW = dH = 0.2 cm
Substituting the given values into the formula to estimate the maximum error in calculating the surface area of the box
S = 2{(90(0.2)+50(0.2)) + (90(0.2)+90(0.2)) + (50(0.2)+90(0.2))
S = 2{18+10+18+18+10+18}
S = 2(92)
S = 184 cm²
Hence, the maximum error in calculating the surface area of the box is 184cm²

Answer:
A Quartic Trinomial is a polynomial whose highest power of the variable is four.
That being said, I believe it is A. 2x^4-2x+6
Step-by-step explanation:
72 people questioned , 12 are going . that means that 16.6..% of which are going , 16.6....% is equal to 1/6 so 210 x 6 = 1260 . the number of students that attend the school would be 1260 if im right but if its how many students attended the play then it would be a 1/6 of 210 which is 35
