Answer:
34.25
Step-by-step explanation:
Lw=A
2l+2w=112
l=6w
2(6w)+2w=112
12w+2w=112
14w=112
w=8
l=48
A=384 ft^2
Answer:
AC and DF
Step-by-step explanation:
We can see that the triangles have a scale factor of 3.
1 * 3 = 3 (AB and DE)
2 * 3 = 6 (BC and EF)
However...
2 * 3 = 6 not 7 (AC and DF)
<h3>
Answer: a^2 - b^2 = (a-b)(a+b)</h3>
The order of the factors does not matter.
So (a-b)(a+b) is the same as (a+b)(a-b)
This is known as the difference of squares factoring rule.
You can FOIL out (a-b)(a+b) and you'd get a^2+ab-ab-b^2. Note how the ab terms cancel leaving us with a^2-b^2. This confirms we have the correct factorization.
Answer: 117.6 millimeters
Step-by-step explanation:
Given , The actual size of beetle = 16 millimeters
Since , the photo of a beetle in a science book is increased to 735% as large as the actual size.
Scale factor to increase the size = 735% = 7.35 [To convert percentage to decimal or fraction we divide it by 100]
Then , the size of the beetle in the photo would be :
(Actual size of the beetle) x (Scale factor)
= (16 millimeters) x (7.35)
= (16 x 7.35) millimeters
= 117.6 millimeters
Hence, the size of the beetle in the photo = 117.6 millimeters
