Let p= x^2-7.

Mathematics
1 answer:
Advocard [28]3 years ago
8 0

Since p = x² - 7, you can substitute/plug in p for x² - 7

So:

(x² - 7)² - 4x² + 28 = 5

(p)² - 4x² + 28 = 5      You can factor out -4 from (-4x² + 28)

p² - 4(x² - 7) = 5        Plug in p

p² - 4p = 5        Subtract 5

p² - 4p - 5 = 0        Your answer is C

a plane is flying at a speed of 200 miles per hour. the pilot plans on flying at this speed for the next 225 miles, plus or minu
harina [27]

The minimum and maximum number of hours the plane will travel at that speed are; at least 0.875 hours and at most 1.375 hours

<h3>How to Solve Absolute Value Inequality?</h3>

We are given that the speed of the plane is 200 miles per hour.

Now, formula for time taken is;

Time = Distance/Speed

If the speed is 225 ± 50 miles, then it means that;

Maximum distance = 275 miles

Minimum distance = 175 miles

Thus, we can say that;

Minimum number of hours = 275/200 = 1.375 hours

Maximum number of hours = 175/200 = 0.875 hours

If the area of a rectangle is 64cm squared, how many different perimeters are possible when the dimensions are whole numbers
FinnZ [79.3K]

Answer:

2 different perimeters, 32 cm and 40 cm

Step-by-step explanation:

Given the area of a rectangle is 64 cm squared.

We know, Area of the rectangle is = length x breath

∴  64 = 8 x 8

Hence the sides can be 8 cm by 8 cm.

So the perimeter of the rectangle is = 8 cm + 8 cm + 8 cm +8 cm

                                                            = 32 cm

Also, Area of the rectangle is = length x breath

∴  64 = 16 x 4

So the perimeter of the rectangle is = 16 cm + 4 cm + 16 cm +4 cm

                                                            = 40 cm

What is the solution to the system: 9x+3y=24 2y+4x=8
egoroff_w [7]

Answer:

x = 4, y = -4

Step-by-step explanation:

9x + 3y = 24

3x + y = 8                       divide both sides by 3

y = 8 - 3x                        subtract 3x from both sides

2y + 4x = 8

2(8 - 3x) + 4x = 8             replace y with 8 - 3x

16 - 6x + 4x = 8                distributive property

-6x + 4x = 8 - 16               subtract 16 from both sides

-2x = -8                            divide both sides by -2

x = 4

y = 8 - 3x

y = 8 - 3(4)                        replace x with 4

y = 8 - 12

y = -4
