Answer: A
48+ 36 = 84
84/4 = 21 groups
there are 21 groups of 4 balloons
Answer:
11
Step-by-step explanation:
-(-7)^2 + (6*-7) + 4
7^2 + (-42) + 4
49 - 42 + 4 = 11
Answer:
Q(0) = -2
Q(1) = 2
Q(-2) = -34
Step-by-step explanation:
Step 1: Define
Q(x) = x³ - 3x² + 6x - 2
Q(0) is x = 0
Q(1) is x = 1
Q(-2) is x = -2
Step 2: Substitute and Evaluate
Q(0) = 0³ - 3(0)² + 6(0) - 2
Q(0) = 0 - 0 + 0 - 2
Q(0) = -2
Q(1) = 1³ - 3(1)² + 6(1) - 2
Q(1) = 1 - 3 + 6 - 2
Q(1) = -2 + 6 - 2
Q(1) = -4 + 6
Q(1) = 2
Q(-2) = (-2)³ - 3(-2)² + 6(-2) - 2
Q(-2) = -8 - 3(4) - 12 - 2
Q(-2) = -8 - 12 - 14
Q(-2) = -20 - 14
Q(-2) = -34
We know that
[area of triangle]=b*h/2
b=15 units
h=8 units
[area of triangle]=15*8/2---------> 60 units ²
see the attached figure
the answer is
60 units ²
