Answer:
Step-by-step explanation:
If (x + 2) is a factor of a polynomial then ( - 2 ) is the zero of that polynomial ⇒ ( - 2 )³ + 2( - 2 )² + 2( - 2 ) + k = 0 ⇒ k = - 4
Answer: 2/3ft or C
Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh. Divide both sides by h: =b
A = 2/5
h = 6/5
b = ?
Next, we can plug the numbers into this equation: =b
Multiply 2 and 2/5: 4/5 / 6/5
Take the reciprocal of 6/5: 4/5 x 5/6 =
÷ =
Answer:
circle with circumference of 6.47m
Step-by-step explanation:
1. $165/$25.50=6.47058823529m
2. she should use a circle because they have the greatest area, the circle should have a circumference of 6.47m.
Opposite angles of an isosceles trapezoid add up to 180.
(That graphic is very blurry. I hope I can read it correctly.)
14x + 3x + 10 = 180
17x = 170
x = 10
