Answer:
d
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) - g(x)
= x³ - 2x + 6 - (2x³ + 3x² - 4x + 2) ← distribute parenthesis by - 1
= x³ - 2x + 6 - 2x³ - 3x² + 4x - 2 ← collect like terms
= - x³ - 3x² + 2x + 4 → d
4 times 2 is 8 and 8-4 is 4 so 4 X10 is 40 plus 8 is 48

Step-by-step explanation:
Answer: Area = 389.5cm^2
Explanation:
Area = 104.5cm^2
Width = 9.5cm
Find Length:
L = A/W
L = 104.5/9.5
L = 11cm
Find the enlargement:
let x be the enlargement:
9.5cm + x = 19cm
x = 19 - 9.5
x = 9.5cm
Thus, the enlargement is 9.5cm.
L (after enlarging) = 11 + 9.5 = 20.5cm
W (after enlarging) = 19cm
Find area after enlarging:
A = 20.5 x 19
A = 389.5cm^2
6(3)[(3)-1] + 4
B(rackets) I(ndicies) D(ivision) M(ultiplication) A(ddition) S(ubtraction)
6(3) (2) + 4
