Answer:

<h2><u>4x² - 9</u></h2>

Step-by-step explanation:

The area of the rectangle = (2x + 3)(2x - 3)

                                              = (2x)² - (3)²

                                               = <u>(4x² - 9)</u>

Solve the following equation for x.<br>m (2-x)=3-y​
Evgesh-ka [11]

Answer:  m=−y+3−x+2

x=2m+y−3m

Step-by-step explanation:  

m(2−x)=3−y

Step 1: Factor out variable m.

m(−x+2)=−y+3

Step 2: Divide both sides by -x+2.

m(−x+2)−x+2=−y+3−x+2

m=−y+3−x+2

__________________________________________________

m(2−x)=3−y

Step 1: Add -2m to both sides.

−mx+2m+−2m=−y+3+−2m

−mx=−2m−y+3

Step 2: Divide both sides by -m.

−mx−m=−2m−y+3−m

x=2m+y−3m

One angle of a triangle is 30° more than the smallest angle. The largest angle is the sum of the other angles. Find the measures
vladimir1956 [14]

Answer: \boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}

Step-by-step explanation:

Let the smallest angle be x.

Then, the middle angle is x+30.

The largest angle is 2x+30.

Angles in a triangle add to 180 degrees, so:

x+x+30+2x+30=180\\\\4x+60=180\\\\4x=120\\\\x=30

So, the angles measure \boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}
