Factor completely, then place the answer in the proper location on the grid. 49x 2 + 42xy + 9y 2

Step-by-step explanation:

We are given that an expression

We have to find the factor of given expression

Identity:

Using the identity,then we get

Hence, the factor of given expression is given by

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

∠cbe and ∠deb are same-side interior angles.
