Answer:
-6
Step-by-step explanation:
first you crossover negative 8 to make it positive then you add to -14
Answer:
StartRoot 2 squared + 6 squared EndRoot
Step-by-step explanation:
we have
A(4,3) and B(-2,1)
we know that
the formula to calculate the distance between two points is equal to
substitute the given values
therefore
StartRoot 2 squared + 6 squared EndRoot
7.211; Starting from the left to right, x1=3 x2=7, y1=2 y2=8. Plug these in to the distance formula
(7-3)^2+(8-2)^2
(4)^2+(6)^2
16+36
sqrt 52
7.211
Answer:
a) b ≈ 100
b) m ≈ 30
Step-by-step explanation:
Answer:
3 inches
Step-by-step explanation:
(14+2x) × (15+2x) = 2(14×15)
210 +30x +28x + 4x² = 420
4x² + 58x - 210 = 0
2x² + 29x - 105 = 0
2x² + 35x - 6x - 105 = 0
x(2x + 35) - 3(2x + 35) = 0
(x - 3)(2x + 35) = 0
x = 3, -35/2(not possible)
