Answer:
1346cm
Step-by-step explanation:
First of all it is fringe, not french or friends.
Now, as we know that perimeter'P' of a rectangular is given by
P=2(length +width)
Given
length=435 cm
width=238 cm
P=2(435 +238) => 1346cm
Therefore, Rhiannon needs to purchase 1346cm of fringe
Answer: The measures of the angles are 64.6 degrees and 25.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees.
x can be one angle, and (x-39.2) can be the other
x + (x-39.2) = 90
2x - 39.2 = 90
add 39.2 to both sides
2x = 129.2
divide each side by 2
x = 64.6
find the measure of the other angle
64.6-39.2 = 25.4
The measures of the angles are 64.6 degrees and 25.4 degrees.
Answer:
A
Step-by-step explanation:

The answer is D.
Explanation:
I decided to start with 6 because it seemed to be the easiest. So you would out 6 in the place of ‘z’
6 ( 6 - 6 ) = 0
Here you would do the parentheses first
6 ( 0 ) = 0
6 * 0 = 0
0 = 0
You’re not done bc it could be both 6 and -6 So input where ‘z’ is and you should get
-6 ( -6 - 6 ) = 0
-6 ( -12 ) = 0
72 doesn’t equal 0
Hope this helped
