Perimeter is 2 times the length plus 2 times the width.
Area is length times width.
Perimeter = (2 x 20) + (2 x 15) = 40 + 30 = 70 inches.
Area = 20 x 15 = 300 square inches.
Answer:
y=-1.5
X=1.75
Step-by-step explanation:
Yuh arrange the equations in order for easy subtracting of the equations.
-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.
6x+3y=6
3y=-6x+6 then divide both sides by three to get y
y=-2x+2
now arrange
y=-2x+2
y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x

Salut!
Alecu ar citi in 12 zile 14 x 12 = 168 de pagini (atatea pagini are cartea);
O saptamana are 7 zile, asa ca 168 ÷ 7 = 24 de pagini trebuie sa citeasca zilnic Alecu ca sa inapoieze cartea la sfarsitul celor 7 zile;
Succes!
