Answer:
2
Step-by-step explanation:
2*2=4*2=8
128.79 *.30 =38.937
128.79-38.937=89.853
So with a 30% discount 128.79 is 89.853
complex roots occur in conjugate pairs
given 2 - 3√5 is a root then 2 + 3√5 is also a root
one of the other roots is 2 + 3√5
there are 2 roots of - 4
one of the other roots could be another - 4
Answer:
A = 3/2 a² + 4b²
Step-by-step explanation:
The area of a trapezoid is:
A = ½ (w₁ + w₂) h, where w₁ and w₂ are the lengths of the parallel sides and h is the height.
The area of a rectangle is:
A = wh, where w is the width and h is the height.
The total area is:
A = ½ (a + 2a) (a) + (b) (4b)
A = 3/2 a² + 4b²
