Which expression can you simplify by combining like terms?

Sonbull [250]

Answer:

$6 {d}^{2} + 5cd - 3dc + 8$

Step-by-step explanation:

b/c we can substructure 5cd and 3dc b/c it doesn't matter if the place of cd and dc change. what I mean if 5 ×3=15 and it is the same with 3×5=15 both of the product are the same but, if it is - and ÷ it wil be wrong for example 5-3=2 but 3-5= -2

What is the equation of a circle that has a center at (-4, 10) and a radius of 8?

mars1129 [50]

Answer:

The equation of the circle is $(x + 4)^2 + (y - 10)^2 = 64$ , third option is correct.

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center $(x_0,y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

Center at (-4, 10)

This means that $x_0 = -4, y_0 = 10$ .

Radius of 8:

This means that $r = 8$ . So

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - (-4))^2 + (y - 10)^2 = 8^2$

$(x + 4)^2 + (y - 10)^2 = 64$

The equation of the circle is $(x + 4)^2 + (y - 10)^2 = 64$ , third option is correct.

Colin buys a car for £45500. It decreases in price 6% per year. How much will it be worth in 3 years?

just olya [345]

Answer:

The answer is 33,710 euros.

Step-by-step explanation:

Start by multiplying 45,550 by 6%. This will give 2,730. over the next three years the price decreases, so multiply 2,730 by 3, which is 8,190. Finally, subtract 45,550 by 8,190 to get 33,710.
