A ) y = 2(3) + 7
y = 15
b ) y = 2(-3) + 7
y = 1
Answer:
42.21 ft^2
Step-by-step explanation:
The formula: A=1
/2b √ c2﹣b2
c=hypotenuse
b=base
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
I think you would have to multiply $4.92 and 6... if so the answer would be $29.52 for the unit price.
I think 80%
I also got stuck on it and searched it up I think its 80% but if I'm wrong I'm sorry
