5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2

First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2

16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:

Multiply the numbers 16 x 2

16 x 2 = 32

Now multiply the numbers 4 x 2

4 x 2 = 8

Now Multiply the numbers 4 x 2 again

4 x 2 = 8

= 32xy - 8x- 8y

Factor 8 from the expression

Final Answer:
8(4xy-x-y)

have a great time.

Step-by-step explanation:

1. 48

= 16 × 3

= 48

2. 25

= 27 -7 + 5

= 32 - 7 

= 25

3. 9

= 17 - 8

= 9

4. 36

= 144 ÷ 36 × 8 + 4

= 4 × 8 + 4

= 32 + 4 

= 36

5. 2

= 32 ÷ 16

= 2

6. 10

= 16 - 15 + 9

= 25 - 15

= 10

7. 16

= 9 + 25 - 2 × 9

= 9 + 25 - 18

= 34 - 18

= 16

Two people share £350 in the ratio 1 : 6. Calculate each share.

EleoNora [17]

Answer:

£50 and £300

Sum the parts of the ratio 1 + 6 = 7 parts

Divide the amount by 7 to find the value of one part of the ratio

£350 ÷ 7 = £50 ← value of 1 part of ratio

Hence

1 person receives £50

the other person receives 6 × £50 = £300

1. The diameter of one side of a 10-foot log is approximately 13 inches. The diameter of the other side of the log is approximat

LuckyWell [14K]

To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³
