Answer:
There are 6 equilateral triangles
you get an isosceles triangle
the height of the equilateral triangle is 4
this is all I have so far :)
Answer:
f=10
Step-by-step explanation:
I don't know a formula for this but I can see that <CRE is a 90° angle so 7f+2f=90 and if f=10 7f=70 and 2f=20 which fits
A^2 + 2AB + B^2 = (A + B)^2 ==>
16X^2 + 40X + 25 =
= (4X)^2 + 2*4*5X + 5^2 =
= (4X + 5)^2

Answer:
a) 1 in : 6 in
b) P=32 inches
A =60 inches ^2
c) P= 16 ft
A = 15 ft ^2
Step-by-step explanation:
The drawing is 6 inches tall, while the real flag is 3 ft tall
Change ft to inches
3 ft * 12 inches/1ft = 36 inches
drawing : real life
6 36
Divide each by 6
1 6
The scale is 1 to 6
So for every 1 inch on the drawing, there is 6 inches in real life
b) P= 2(l+w) = 2(10+6) = 2(16) = 32 inches
A = l*w = 10*6 =60 inches ^2
C)
The drawing is 10 inches by 6 inches
Multiply by the scale factor of 6
Real life is 60 inches by 36 inches
Divide by 12 to get back to ft
5ft by 3 ft
P= 2(l+w) = 2(5+3) = 2(8) = 16 ft
A = l*w = 5*3 =15 ft ^2
