Answer:

-9x^{9} y^{5}

Step-by-step explanation:

(-8x⁴y³)(2x⁵y²)+7x⁹y⁵  (grouping like terms)

= (-8)(2) (x⁴x⁵) (y³y²) +7x^{9} y^{5}

= -16 x^{4+5} y^{3+2 } + 7x^{9} y^{5}

= -16 x^{9} y^{5} + 7x^{9} y^{5}

= (-16 + 7)x^{9} y^{5}

= -9x^{9} y^{5}

Tom was driving 20.3 meters per second in a 45 mile per hour zone. Was Tom speeding? Explain using a unit conversion as well as
My name is Ann [436]

Answer:

Tom was speeding.

Step-by-step explanation:

The driving speed of Tom = 20.3 meters per second.

Speed allowed in the zone = 45 miles per hour zone.

Since the unit of speed allowed is given in miles per hour but the speed of tom is given in meters per second. So, first, we have to convert the meter per second into mile per hour then we can compare and find that Tom is speeding or not.  

1 mile = 1609.34 meters

1 hour = 3600 second

Now convert 20.3 into mile per hour.

20.3 meters per second. = (20.3 / 1609.34)*3600 = 45.40981 mile per hour.

Since Tom’s speed is more than the allowed speed so he is speeding.

The fact your family Drove from Arizona to Malibu ,California to spend a week at the beach they drove
prisoha [69]
To solve this question, you need to do 421 divided by 9.

421 divided by 9 will get you a long number, which is 46.7777778.

Round your number up by the hundredths place. You will get 46.78.

The average speed in miles per hour would be 46.78 MPH.

Solve the equation by taking the square root 4(x+1)^2=100
Naddika [18.5K]

Answer:

Step-by-step explanation:

4(x+1)²=100

(x+1)²= 5²

(x+1)²- 5² = 0

(x+1-5)(x+1+5) = 0  by identity : a² - b ² = (a - b) (a+b)

(x - 4 ) (x+6) =0

x - 4 = 0 or x+6 = 0

x = 4  or x = - 6
