Answer:
£23
Explanation:
6x10=60
2x1.5=3
3.14x2^2=12.566
60-3-12.566=44.433
44.43/10=4.43
5 bags
5x4.60=23
=£23
Step-by-step explanation:
let's look at the last line :
x³ + 8x - 3 = Ax³ +5Ax + Bx² + 5B + Cx + D
since we find A, B, C, and D by simply comparing the factors of the various terms in x (or constants) in both sides of the equation, we need to combine a few terms on the right hand side (so that we have one term per x exponent grade).
x³ + 8x - 3 = Ax³ + (5A + C)x + Bx² + (5B + D)
by comparing now both sides, to make both sides truly equal, the factors have to be equal.
A = 1 (the same as for x³ on the left hand side).
B = 0 (a we have no x² on the left side).
5A + C = 8 (a 8 is the factor of x in the left side).
5×1 + C = 8
5 + C = 8
C = 3
5B + D = -3 (as the constant term is -3 on the left side).
5×0 + D = -3
D = -3
so, the 4th answer option is correct.

Answer:
<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
Step-by-step explanation:
Creative Landscaping has 60 yard of fencing with which to enclose a rectangular garden.
If the garden is X yards long, express the Gardens area as a function of length
Let x be the length of garden
So perimeter of rectangle = 60 yard
Perimeter = 2 * ( Length + width)
60 = 2 * ( x + width)
Width = 60/2 - x
Width= 30 - x
<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
