Question

3.2[x+1]=10.Find x?
4.If 3x+6=2(x+6) and y=3x.find y?
5.Expand
a)(x+1)°2
b)(x-2)°2​

Answer 1

Step-by-step explanation:

Ques.3. 1. 2(x+1)=10

2x+2=10

2x=10-2

2x=8

x=8/2

x=4 (Ans)

Answer 2

Step-by-step explanation:

2(x+1)=10

2x+2=10

2x=8

x=8/2

x=4

3x+6=2(x+6)

3x+6=2x+12

x=6

y=3x

y=3(6)

y=18

$( {x + 1)}^{2}$

${x}^{2} + 2.x.1 + {1}^{2}$

${x}^{2} + 2x + 1$

$( {x - 2)}^{2}$

${x}^{2} - 2.x.1 + {2}^{2}$

${x}^{2} - 2x + 4$
