OK so each block is 3cm tall and 3.5cm wide (because 2 are 7cm wide)
so to measure the perimeter count all the side values for example:
the 5 squares at the bottom which measure 3.5cm each adds up to a total of 17.5cm then if you add the top 2 flat sides that's another 2, 3.5cm which adds up to 7cm. 17.5cm + 7cm = 24.5cm then their are 3 walls on each side measuring 3cm each so 3cm * 6 = 18
24.5cm + 18cm = 42.5cm (I think this is correct)
The options are;

b)8x+24
c)2x^4+24
d)4x^2+24x+35

dimensions of the photograph
length - 7 inch
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides
Perimeter = 2(7 + 2x) + 2(5 + 2x)
= 14 + 4x + 10 +4x
= 24 + 8x
correct answer is b
If you want rough hours, it would be 6. Round the 10:52 to 11, and the 4:53 to 5, its 6 hours. You want specifics though, it would be exactly 6 hours and 1 minute.

Answer:
1
Step-by-step explanation:
The right triangle is isosceles, so x = 45° and tan(x) = 1.
__
You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.
