Combine like terms.

-14cd + 15cd - 15cd = -14cd
-2c²d² + 9c²d² = 7c²d²

7c²d² - 14cd is your answer

hope this helps

URGENT!! DESPERATE!! GEOMETRY REFLECTIONS!!! PLEASE INCLUDE EXPLANATION BOGUS ANSWERS WILL BE REPORTED
serious [3.7K]

When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .

So the final answer is (-1,-2) .

Hannah wants to rewrite 18+12 using the greatest common factor and the distributive property. Which expression should she write?
grigory [225]

Answer:

6(3+2)

Step-by-step explanation:

Distributive property:

ab + ac = a(b+c)

where a = greatest common factor (GCF)

GCF of each factor

18 = 2×3×3

12 = 2×2×3

GCF of 18 and 12 = 2×3

= 6

Therefore,

18 + 12 = 6(3) + 6(2)

= 6(3+2)

Where,

6 = a

3 = b

2 = c

ab + ac = a(b+c)

The city of Orlando’s building a dog park in downtown Orlando dog park will be triangular shaped as shown on the coordinate plan
kiruha [24]

Answer:

Perimeter of the dog park = 15.4 yards

Step-by-step explanation:

Coordinates of the vertices of the given triangle are,

P(1, 2), Q(1, 6), R(-4, 2)

Since distance between the two points (x_1, y_1) and (x_2,y_2) is,

d = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Length of PQ = \sqrt{(1-1)^2+(2-6)^2}

PQ = 4

Length of PR = \sqrt{(1+4)^2+(2-2)^2}

PR = 5

Length of QR = \sqrt{(1+4)^2+(6-2)^2}

QR = \sqrt{25+16}

     = \sqrt{41}

     = 6.4 yards

Therefore, perimeter of the given triangle = PQ + QR + PR

                                                                       = 4 + 6.4 + 5

                                                                       = 15.4 yards
