Answer: a=17 mm length
b=37 mm width
Step-by-step explanation:
P=2a+2b
a -length
b-width
b=2a+3
------------------
108mm=2a+2(2a+3)
108=6a+6
6a=102
a=17 mm
b=17*2+3
b=34+3
b=37 mm
Answer:
c
Step-by-step explanation:
add -x to both sides
multiply both sides by -1/2
the equations don't have the same slope so they aren't parallel
The solpes product doesn't equal -1 so they aren't perpendicular
Answer:
Step-by-step explanation:
Plug into the midpoint formula

Hello, there!
<span>Ten times a number is sixteen more than twice the number. Find the number.
Answer: 2
-----------------------------------------------------------------------------------------------------
Explanation:
</span>
First, let's write the equation.
Ten times a number -- 10x
16 more -- 10x - 16
Twice the number -- 2x
10x - 16 = 2x or 10x = 2x + 16
Let's use the first one: 10x - 16 = 2x
First, let's isolate the x to one side.
10x - 16 = 2x
-10x -10x
-16 = -8x
Now, let's multiply each side by -1 to make them positive
-16 = -8x
*-1 *-1
16 = 8x
Finally, let's divide each side by 8
16 = 8x
---- ----
8 8
Our answer is 2 = x
This means that the number is 2.
I hope I helped!

6 yards is the answer
144π= πr^2*4 (formula)
the pi’s cancel out
divide 144/4
36=r^2
square root 36 to get rid of the r squared
r= 6 yd
