You would change it because it is the simplest answer
Answer:
$666
Step-by-step explanation:
I think you just need to do 2664×0.25 ( which you can do it on a calculator ) , is
<u><em>$666</em></u>
Answer:
so basically
the area of the square; (5cm)^2 = 25cm^5
the area of the triangle; (4cm.5cm)/2 = 10cm^2
which means that r = √25cm^2/10cm^2 = √25/10 cm^2 or √10/25 cm^2
english is not my first language so i do not know what combined means but if u explain a little more i will try to help u
-> ok edit edit;
1cm/5in. = r
5cm => 25in.
z^2= area of a square so
25in.25in= 625 in^2
4cm => 20in.
5cm => 25in.
h.b/2 = area of a triangle so
20in.25in./2 = 250in.^2
250in.^2 + 625in.^2 = 875in.^2
so answer B
Answer:
x=16
Step-by-step explanation:
If the triangles are similar then their sides are in proportion.
Set the proportions 20/(3x+8)=(x-1)/(x-1+27)
solve for x,
cross multiply
20(x+26)=(x-1)(3x+8),
distribute
20x+520= 3x² +8x-3x-8,
combine like terms
3x²-15x-528=0
solve using quadratic formula
x=16 and x= -11 reject because we cannot have negative measurements
1/9x - 1 is the answer.
this is because a perpendicular line has opposite reciprocal slope
