Area: 60
Explanation: we know the height of the square therefore we know all of its dimensions. We can multiply 3x2 to get the height, which is 6. And add 3 to 7 to get the length, which is 10.
The formula for area is <em>A=wl</em>
<em>A=6(10)</em>
<em>A=60</em>

8 ) 712
8 goes into 71 8 times; the product of 8 and 8 is 64.
Subtracting this 64 from 71, we get 7, to which we append 2: 8 ) 72.
8 divides evenly into 72: 9.
Thus, the desired quotient is 89.
Answer: d) q--->r
Step-by-step explanation:
This is an example of substitution. We know that p=q, and need to make p=r.
Lets assume p=3. Then q must equal 3. Then r must equal three. Thus, q=r.
If x=y and x=z then y=z
