3xz+(5x+3z)(7x-2xz+y-4z)

Simplify^

−10x2z+−6xz2+35x2+5xy+4xz+3yz+−12z2

Step-by-step explanation:

Let's simplify step-by-step.

3xz+(5x+3z)(7x−2xz+y−4z)

Distribute:

=3xz+(5x)(7x)+(5x)(−2xz)+(5x)(y)+(5x)(−4z)+(3z)(7x)+(3z)(−2xz)+(3z)(y)+(3z)(−4z)

=3xz+35x2+−10x2z+5xy+−20xz+21xz+−6xz2+3yz+−12z2

Combine Like Terms:

=3xz+35x2+−10x2z+5xy+−20xz+21xz+−6xz2+3yz+−12z2

=(−10x2z)+(−6xz2)+(35x2)+(5xy)+(3xz+−20xz+21xz)+(3yz)+(−12z2)

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
