Question

use the distrubutive law to expand the following

10(6g+7)





5(3e+8)





8(s+7)





4(2+a)





7(x+5)





3(6+a)





9(9-x)





5(j-4)

Answer 1

[AI-generated answer — Bot GPT 3.5]

10(6g+7) = 10 * 6g + 10 * 7 = 60g + 70

5(3e+8) = 5 * 3e + 5 * 8 = 15e + 40

8(s+7) = 8 * s + 8 * 7 = 8s + 56

4(2+a) = 4 * 2 + 4 * a = 8 + 4a

7(x+5) = 7 * x + 7 * 5 = 7x + 35

3(6+a) = 3 * 6 + 3 * a = 18 + 3a

9(9-x) = 9 * 9 - 9 * x = 81 - 9x

5(j-4) = 5 * j - 5 * 4 = 5j - 20

Answer 2

6i(t-v)

2d(v+m)





5c(2w-t)





6e(s+p)





d(x+9s)





5a(2x+3v)





5j(r+7p)





I(n+4w) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer 3

[AI-generated answer — Bot GPT 3.5]

6i(t-v) = 6i * t - 6i * v = 6it - 6iv

2d(v+m) = 2d * v + 2d * m = 2dv + 2dm

5c(2w-t) = 5c * 2w - 5c * t = 10cw - 5ct

6e(s+p) = 6e * s + 6e * p = 6es + 6ep

d(x+9s) = dx + 9ds

5a(2x+3v) = 5a * 2x + 5a * 3v = 10ax + 15av

5j(r+7p) = 5j * r + 5j * 7p = 5jr + 35jp

I(n+4w) = In + 4Iw

Answer 4

When expanded, 4(3x+6y) gives 12x+24y. Find two other expressions that expand to 12x + 24y.

Answer 5

In a school classroom there is one teacher as well as an unknown number of boys and girls.

a If the number of boys is b and the number of girls is g, write an expression for the total
number of people in the classroom, including the teacher.
b The teacher and all the students are each wearing two socks. Write two different expressions
for the total number of socks being worn, one with brackets and one without.

Answer 6

[AI-generated answer — Bot GPT 3.5]

a) The total number of people in the classroom, including the teacher, can be expressed as b + g + 1.

Answer 9

Write an expression for each of the following and then expand it.

b
A number, x, has 3 added to it and the result is multiplied by 5.
A number, b, has 6 added to it and the result is doubled.
A number, Z, has 4 subtracted from it and the result is multiplied by 3.
A number, y, is subtracted from 10 and the result is multiplied by 7.

Answer 10

[AI-generated answer — Bot GPT 3.5]

1) The expression for "A number, x, has 3 added to it and the result is multiplied by 5" is: 5(x + 3)

Expanding it: 5x + 15

2) The expression for "A number, b, has 6 added to it and the result is doubled" is: 2(b + 6)
Expanding it: 2b + 12

3) The expression for "A number, Z, has 4 subtracted from it and the result is multiplied by 3" is: 3(Z - 4)
Expanding it: 3Z - 12

4) The expression for "A number, y, is subtracted from 10 and the result is multiplied by 7" is: 7(10 - y)
Expanding it: 70 - 7y
