A. m^2 - 36 = 0
m^2 = 36
m = √36 = 6 or -6
b. 3x^2 + 15 = 0
3x^2 = -15
x^2 = -5
x = √(-5) not possible unless complex numbers is applied
-1 = i^2
x = √(-5) = √(5i^2) = √5i
c. 4d^2 + 16 = 16
4d^2 = 0
d^2 = 0
d = 0
Hope it helped!
Substitute on equation 2, y = -4x + 7. so equation 1 becomes 2x - (-4x + 7) = 6x - 7 = 5. 6x = 12, so x = 2. from above, y = -4x+7 = -4(2) + 7 = -1
Answer:
42°
Step-by-step explanation:
→ Since this quadrilateral is a parallelogram, ∠S is equal to ∠R. Let's represent the situation in terms of equations
6x + 6 = 3x + 24
→ Minus 3x from both sides to collect the 'x' terms
3x + 6 = 24
→ Minus 6 from both sides isolate 3x
3x = 18
→ Divide by 3 on both sides isolate x
x = 6
<em>⇒ The value of x is 6, but this isn't the measurement of ∠S, we need to substitute in x = 6 into the expression 6x + 6</em>
6 (6) + 6 ⇔ 36 + 6 = 42°
Answer: The bag is $36 + 18% which equals to $42.48 so thats the total.
He paid 18% interest which is $6.48
