Answer:

s= 7 inches

Step-by-step explanation:

Let the side length be x

Area of square = side × side OR [tex]side^{2}[/tex]  (lets put x in place of side)

                   [tex]49^{2}[/tex] = x

                      7 = x

Side length = 7 inches                        

Answer:

7 inches

Step-by-step explanation:

Area of a square = 49 sq. inches

side *side = 49

       side = [tex]\sqrt{49}=\sqrt{7*7} = 7 \ inches[/tex]

Answer:

x^3 -x^2 + 25x - 25

Step-by-step explanation:

x = 1

x = 5i

x = -5i

(x - 1)(x - 5i)(x + 5i)

Multiply

(x - 1)(x^2 + 5ix - 5ix + 25) *Remember that i multiplied by i equals negative and in this situation, one of the variables was already negative, so negative multiplied by negative is positive*

(x - 1)(x^2 + 25)

Multiply again

x^3 + 25x -1x^2 - 25

x^3 -x^2 + 25x - 25

Answer:

8.9(2)

Step-by-step explanation:

8.9/2 is division.

8.9+2 is addition.

(8.92) is just adding 2 onto 8.9 which extends the number, not multiplies.

Step-by-step explanation:

you double the first unit by multiplying it by 2

Answer: 6

Step-by-step explanation:

Since fourths are basically eights cut into half, you can shade in the second empty diagram to look just like the first one. You will see that you shaded in 6 parts.

That means that 6/8 is the answer.

So sorry if this is wrong!! :((

Answer:

Slope: 6/5

Step-by-step explanation:

For this problem, you'll need to apply the slope formula Y2-Y1

                                                                                             X2-X1.

Let's now assign each number their position in the formula. The first set of parentheses, (-2,-1) is going to translate to (x1,y1). (3,5) will translate to (x2,y2). Now, when you put it all together, you get 5-(-1) / 3-(-2). This would give you 6/5. That would be your slope. You can then proceed to graph it. Hope this helped! :))

No

Step-by-step explanation:

If you graph this function, you'll find that it looks like a vertical line, straight up and down. In a function, each x-value has to have exactly one y-value. In this function, however, any y-value you plug in gives you the same x-value: -2.

The one x-value, -2, has an infinite number of corresponding y-values, so this is definitely not a function.

Step-by-step explanation:

Complementary is adding up to 90 degrees. depends what the other angle is/one of the pair. Subtract that by 90 and you find the other angle.

The number of miles traveled by Kai's family as required in the task content is; 73 miles.

It follows from the task content that the number of miles traveled by Kai's family on the third day is to be determined.

On this note, since the family travelled 365 miles on the first day and travelled 20% farther on the third day;

The number of miles traveled on the third day can be modelled as;

= 20% of 365

= (20 / 100) × 365

= 73 miles.

On this note, the number of miles traveled on the third day is; 73 miles.
