Answer:
P= 30 cm
Step-by-step explanation:
Formula for Rectangle Perimeter P=2(l+w)
P=2(10+5)
P=2(15)
P=30
The equation would be 2x+3 so when you plug it in it's 2(-2)+3 which simplify to -4+3 which is -1
The area would be 18 inches and you would need a ten by ten square to cover it.
4 more than 4 times x is 45 the answer will be x=41/4
Draw out a number line. Make sure 4 is on the number line. At this location, plot an open circle. The open circle indicates "do not include this endpoint as part of the solution set". We shade to the right of this open circle.
Visually this describes all real numbers that are larger than 4.
