Answer:

x = 5, x = 11

Step-by-step explanation:

Set f(x) = 0 and solve for x.

0 = (x -8)² -9

9 = (x -8)² . . . . . add 9

±√9 = x -8 . . . . . take the square root

±3 +8 = x . . . . . . . add 8

That is, ...

x = 8 -3 = 5 . . . . lesser x

x = 8 +3 = 11 . . . greater x

Justin bought 5 apples and 4 oranges for £45. On another occasion, he bought 2 apples and 8 oranges which cost £50. Find the cos

Vitek1552 [10]

Answer:

the cost of 3 apples and 7 oranges be £15 and £35 respectively

Step-by-step explanation:

Let us assume the apple be x

And, the oranges be y

Now according to the question

5x + 4y = £45

And,

2x + 8y = £50

Multiply by 2 in equation 1

So,

10x + 8y = £90

2x + 8y = £50

8x = £40

x = £5

And, y be

5(£5) + 4y = £45

£25 + 4y = £45

4y = 20

y = £5

So, the cost of 3 apples and 7 oranges be £15 and £35 respectively

QveST [7]

The question has missing details

The missing options are:

A. 188,000 square yards

B. 138,000 square yards

C. 600 square yards

D. 300 square yards

See attachment 1 for the missing diagram

Answer:

B. 138,000 square yards

Step-by-step explanation:

The figure can be divided into two shapes (see attachment 2)

From attachment 2,

The dimension of the big rectangle is 1300ft by 800ft

The dimension of the small rectangle is 500ft by 400ft

So, the area is:

Area of the big rectangle added to the area of the small rectangle

i.e.

$Area = 1300 * 800 + 500 * 400$

$Area = 1040000 + 200000$

$Area = 1240000ft^2$

Convert to $yd^2$ by dividing by 9

$Area = 1240000yd^2 /9$

$Area = 137777.777778\ yd^2$

From the list of given options, the closest to the area of the diagram is

B. 138,000 square yards
