The area of a triangle is $A= \frac{1}{2} bh$ . solving for h (height) we get:
$h= \frac{2A}{b}$

Order the following numbers from least to greatest.

Marianna [84]

Answer:

$\Huge \boxed{-2.3, \ \frac{-1}{3} , \ \sqrt{3} , \ \sqrt{7} , \ 5.1}$

$\rule[225]{225}{2}$

Step-by-step explanation:

We will convert the values into decimals for simplicity.

$\sqrt{7} = 2.64575131106...$

$-2.3=-2.3$

$\sqrt{3} = 1.73205080757...$

$5.1=5.1$

$\displaystyle \frac{-1}{3} =-0.333333333...$

Arranging from least to greatest:

$\displaystyle -2.3, \ \frac{-1}{3} , \ \sqrt{3} , \ \sqrt{7} , \ 5.1$

$\rule[225]{225}{2}$

The equation -3(1+x) = -3x + 1 has no solutions. Show algebraically why this is true, and explain your reason

KiRa [710]

−3(1+x)=−3x+1
Step 1: Simplify both sides of the equation.
−3(1+x)=−3x+1
(−3)(1)+(-3)(X)=-3x+1
(Distribute)
−3+ −3x=−3x+1
−3x−3=−3x+1
Step 2: Add 3x to both sides.
−3x−3+3x=-3x+1+3x
−3=1
Step 3: Add 3 to both sides.
−3+3=1+3
0=4
Answer:
There are no solutions.
