Answer: (x−3)(x+7)
=(x+−3)(x+7)
=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)
=x^2+7x−3x−21
=x^2+4x−21
Consider this option (see the attachment).
Note, that the formula (a+b)²=a²+2ab+b² is used.
The answer is √32 because the triangle is an isosceles triangle meaning two sides are the same length so two sides are 4 and then you use the Pythagorean theorem to find the value of r
16÷2= 8minivans x 5 other cars, 40 other cars is the total in the parking lot. Your answer is 40 other cars because you already know the 16 minivans.
Lets O is the center of the circle and Lets A is a point cut on CD from O
mCD = m<COD
OA is perpendicular bisector of CD so OA = 1/2 CD = 1/2(12.7) = 6.35
Sin (DOA) = AD/OD = 6.35 / 9.06
Sin DOA = 0.7009
<DOA = 44.5°
<COD = 2 x 44.5°
<COD = 89°
mCD = <COD = 89°
Answer: 89°
