Answer:She should plant 32 daisies.
Step-by-step explanation:4:2 can be expressed as 2:1 .
2+1 =3
48/3 = 16(value of one)
16 x 2 = 32
A. 20 for $2.47 is about 12 cents per ounce (0.1234)
32 oz for $2.99 is about 9 cents per ounce (.093)
40 oz for $3.79 is about 9 cents an oz (0.095)
B. The best deal is 32 ounce for $2.99 but not by much over 40 oz for 3.79
Angle measures are ∠M = 90° and ∠L = 24°
Step-by-step explanation:
- Step 1: In the figure, LM is a tangent to the circle N at point M.
Tangents create right angles at the point of contact with a circle.
So ∠M = 90°
- Step 2: Sum of angles in a triangle is equal to 180°
⇒ ∠L = 180° - (∠M + ∠N) = 180° - (90° + 66°)
= 180° - 156° = 24°

cross multiply 9*20 then divide by 8
X²+3x-21=0
1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2
2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21
Answer: the product of the 2 solutions of this equation is -21
