The required scale is 2 cm t 5 in
This means that 2cm on the drawing would represent 5 inches on the actual flower. If the flower is 8 inches in real life, then the equation would be as shown below
2cm = 5 in
xcm = 8 in
where x represent the height of the flower on the drawing. By cross multiplying, we have
x * 5 = 2 * 8
5x = 16
x = 16/5
x = 3.2
The height of the tree on the drawing would be 3.2 cm
Answer:
y = 6.4
Step-by-step explanation:
1.1 = 13.9 - 2y
-12.8 = -2y
6.4 = y
Answer:

(x - 3)(x + 5) + (x - 3)(2x - 1)
We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1
(x - 3)(3x + 4) is the final answer.
As per the isosceles triangle theorem, if the two base angles are congruent then the legs are also congruent, so we must set the two legs equal to each other:
2z - 15 = 9
Add 15 to both sides:
15 - 15 = 0
15 + 9 = 24
Divide 2 from each side:
2z = 24
2z/2 = z
24/2 = 12
z = 12
Hence, the answer would be D: z = 12
