Answer:

10x+30

Step-by-step explanation:

Distributive property is distributing what is in the parentheses.

To do that on this problem you have multiply each of these numbers by 10!

10 times x is 10x

10 times 3 is 30

Put them back together and you get 10x+30!

I hope this helps, and have a great day! :)

P.S. If you need a better explanation I can help. I just didn't want to make this to long.  :D

What is the value of x in the equation 2(x−3) 9=3(x 1) x? x = −3 x = −1 x = 0 x = 3
Masja [62]

The solution of the linear equation is x = 0.

<h3>What is the linear equation?</h3>

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression.

Linear equations are the equations of degree 1.

The given linear equation is;

\rm 2(x-3)+ 9=3(x+ 1) +x

The value of x is determined in the following steps given below.\rm 2(x-3)+9=3(x+1)+x\\\\2x-6+9=3x+3+x\\\\\ 2x+3=4x+3\\\\3-3=4x-2x\\\\0=2x\\\\x=0

Hence, the solution of the linear equation is x = 0.

BD=BC=x

  • (x+5)²+x²=7²
  • x²+10x+25+x²=49
  • 2x²+10x- 24=0
  • x²+5x-12=0
  • x=1.8

BC= 1.8 cm

Area of ABC= 1/2*1.8*7= 6.3 cm²
