I believe that the answer is 7 because it is in the tens place.
Sorry misunderstood the Question the other user is correct
originally had a 2
<span>2(30)+2x=860
This is because the 4 sides of the rectangle add up to the perimeter.
The unknown side is x, and there are two of those, and there are also two sides of 30.
They all add up to the perimeter.
So:
2(30) + 2x = 860</span>
Answer:
A| 12, 3
Step-by-step explanation:
The polynomial can be factored by looking for factors of 36 that sum to -15. The sum being negative while the product is positive means both factors will be negative. The answer choices suggest ...
y = (x -12)(x -3)
A quick check shows this product is ...
y = x^2 -12x -3x +36 = x^2 -15x +36 . . . . as required
The factors are zero when x is either 12 or 3.
The zeros of the equation are 12 and 3.

Once you realize the constants in the binomial factors both have a negative sign, you can immediately choose the correct answer (A).
Or, you can use Descartes' rule of signs, which tells you that the two sign changes in the coefficients (+-+) mean there are 2 positive real roots.
Answer:
#2, AB is congruent to AD
Step-by-step explanation:
AB is congruent to AD.
since the bottom sides are corresponding, and the middle sides are corresponding, then if the outside sides are corresponding, then CAB is congruent to CAD
