Answer:
8
Step-by-step explanation:
=(7−(−1))2+(4−4)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
=(8)2+(0)2‾‾‾‾‾‾‾‾‾‾√
=64+0‾‾‾‾‾‾√
=6‾√4
=8
Answer:
C. -4x - 1
Step-by-step explanation:
Distribute the term outside of the parenthesis, Multiply each term in the parenthesis by the term outside (do not forget to include the negative sign when multiplying);
Simplify,
PARALLEL slopes always have the same slope no matter what because they are parallel
This problem is a multi step problem. All you have to do is break it down into parts to make it easier. We can start by finding the diameter of the inner circle.
1. circumference = πd (Since the circumference is given as 44, and we know to use 22/7 for π, divide 44 by 22/7 to get d.)
44 / 22/7 = about 14.0 when rounded
2. Now add +8 to the 14 since we know that there are 4 ft. on both sides of the small inner circle.
14 + 8 = 22
3) The last step gave us the diameter of the bigger outer circle. Now, we have to plug in the 22 for d in the formula for circumference to find the circumference of the outer circle.
c = πd → c = 22 * 22/7 = 484/7 (484/7 = about 69 when rounded as a decimal)
4) The last step now is to subtract the circumferences, since the problem was asking for how much greater the outer circle's circumference is than the inner circle.
69 - 44 = 25
Your answer should be about 25 ft.

Answer:
<h2><em><u>
m = 20</u></em></h2><h2><em><u>
a = 48</u></em></h2><h2><em><u>
These are the answers.</u></em></h2>
Step-by-step explanation:
1. m/-8 = -2.5
*-8 = *-8
m = -2.5*-8
m = 2.5*8
<em><u>m = 20</u></em>
2. 7/8a = 42
*8 *8
7a = 336
/7 /7
a = 336/7
<em><u>a = 48</u></em>
<em><u></u></em>
Hope this helped,
