That would be 8.26 meters.
Problem 23
A = 40
B = 3x+1
C = 3x+1
B and C are congruent, so they have the same angle measure
The three angles of any triangle add to 180 degrees
A+B+C = 180
40+(3x+1)+(3x+1) = 180
6x+42 = 180
6x = 180-42
6x = 138
x = 138/6
x = 23
Answer: B) 23
============================================================
Problem 24
AB is the midsegment parallel to XY
So AB is half that of XY
AB = (1/2)*XY
AB = (1/2)*28
AB = 14
Answer: B) 14
============================================================
Problem 25
Note the ratio of the given rectangle's sides: 7/12 = 0.583 roughly
Divide the answer choices in a similar fashion
A) 5/7 = 0.714
B) 14/36 = 0.389
C) 21/36 = 0.583
D) 21/48 = 0.4375
We get the same result in choice C as we did in the original rectangle
Answer: C) 21 ft x 36 ft
Answer:
The answer is 9(a-2)(a+4).
Step-by-step explanation:
Use 
Answer:
x = ± 2
Step-by-step explanation:
given
40 - x² = 0 ( add x² to both sides )
40 = x² or
x² = 40 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
Hi!
Given:
Multiply both sides by 
<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>
<u>Now, for the graph:</u>
-------------------------------------------------------------------------------------------------------------
For < or > signs, it should be an open circle. For 
or 
signs, it should be closed.
Since 
is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.
(looks like you were right!!)
