Answer:
42 units squared
Step-by-step explanation:
break it up into smaller shapes. if you split the big shape at y = 2 and at y=-2, you'll get two triangles and one rectangle.
so the area of the rectangle = l x w
= 4 x 7
= 28
the area of the triangle is ( l x w )/2
= (7 x 2)/2
= 7
the other triangle is the same too
so the area of that is also 7.
now add all areas,
7+7+28 = 42
Answer:
14 is the opposite of -14
Step-by-step explanation:

There is only one repeating number, so we multiply both sides by

or

.

Now subtract the original number we had to both sides, which is the same as

or

So we have:

Divide 9 to both sides:

Multiply the fraction by 10 to get rid of the decimal in the numerator.

Simplify the fraction by dividing the numerator and denominator by 2:
Find cost of pens and mechanical pencils
pen cost=number of pens times cost pe pen
pencost=10 times 0.35=3.50
mech cost=number of mechs times cost pe mech
mechcost=5 times 0.89=4.45
4.45 is more than 3.50
yes, mech cost mre than pens
