$6 for each popcorn and $4 for each soda
Answer:
Step-by-step explanation:
∠D ≅ ∠R
DC ≅ RK
So, If ∠C ≅ ∠K,
Then ΔDCS ≅ ΔRKO by Angle Side Angle congruent. {A S A}
OR
DC ≅ RK
∠D ≅ ∠R
If SD ≅ OR , then
ΔDCS ≅ ΔRKO by Side Angle Side congruent {S A S}
Answer:
You need to know that pairs of two angles are congruent and the pair of sides adjacent to one of the given angles are congruent
Answer: 3x2 + 3x - 7
Step-by-step explanation: The first term is, 3x2 its coefficient is 3
The middle term is, +3x its coefficient is 3
The last term, the constant, is -7
1.Multiply the coefficient of the first term by the constant 3 times -7 = -21
2. Find two factors of -21 whose sum equals the coefficient of the middle term, which is 3
Answer:
I know you could easily solve this just looking at it.
But if you want the algebraic solution:
x + x^2 = 30
x^2 + x -30 = 0
a = 1
b = 1
c = -30
Using the quadratic formula:
x = [ -b +- sqr root (b^2 - 4ac) ] / 2a
x = [-1 +- sqr root (1 - 4 * 1 -30) ] / 2*1
x = [-1 +- sqr root (1 + 120) ] / 2
x = -1 +- sqr root (121) / 2
x1 = (-1 + 11) / 2 = 10 / 2 = 5
x2 = (-1 -11) / 2 = -12 / 2 = -6
Answers are 5 and -6
5 + 5^2 = 30
-6 + (-6)^2 = 30
-6 +36 = 30
