D. It is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
<h3>Given Equation:</h3>
25 - 5x = 5( -x + 5 )
<h3>Solution:</h3>
25 - 5x = -5x + 25
or, 25 - 25 - 5x + 5x = 0
or, x = 0
<h2>Answer:</h2>
<u>Option B. x = 0</u>
<h3>To Check:</h3>
25 - 5x = 5 ( -x + 5 )
or, 25 - 5(0) = 5 ( 0 + 5 )
or, 25 - 0 = 0 + 25
or, 25 = 25
LHS = RHS
Hence, Verified.
Answer:
(x-9)(x-8)
Step-by-step explanation:
I'll do problem 12 to get you started
----------------------------------------
Part (a)
The ratio 3:6:7 means the three sides are 3x, 6x and 7x centimeters long. The x is some positive real number.
The longest side is 7x, which is also 16.1, so 7x = 16.1
Divide both sides by 7 to isolate x
7x = 16.1
7x/7 = 16.1/7
x = 2.3
Now we can calculate the other two sides
3x = 3*2.3 = 6.9
6x = 6*2.3 = 13.8
<h3>The other two sides are 6.9 cm and 13.8 cm</h3>
----------------------------------------
Part (b)
Add up the three sides to get
6.9 + 13.8 + 16.1 = 36.8
<h3>The perimeter is 36.8 cm.</h3>
18b-24c. U take the six times the 3b and then the 6 times the -4c. U “distribute” the six with both values
