Factor the polynomial.
mixer [17]

Answer:

Final answer is choice B. (5x-2y)^2

Step-by-step explanation:

We need to factor the given expression 25x^2-20xy+4y^2

25x^2-20xy+4y^2

=25x^2-10xy-10xy+4y^2

=5x(5x-2y)-2y(5x-2y)

=(5x-2y)(5x-2y)

=(5x-2y)^2

Hence final answer is choice B. (5x-2y)^2

Factor the GCF: 12a3b + 8a2b2 − 20ab3
Harrizon [31]
<span>12a^3b + 8a^2b^2 − 20ab^3

</span>12a^3b = 4ab(3a^2)
8a^2b^2 = 4ab(2ab)
20ab^3 = 4ab(5b^2)

GCF = 4ab

12a3b + 8a2b2 − 20ab3 = 4ab(3a^2 + 2ab - 5b^2)

Solve this system of equations: X=? Y=? ( JUST WRITE THE NUMBER ANSWERS WITH A COMMA BETWEEN THEM)
hjlf

Answer:

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

Step-by-step explanation:

Given:

y=2x                ...............Equation ( 1 )

x=-y+6         ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Substitute Equation  ( 1 ) in Equation ( 2 ) we get

x=-2x+6\\\\3x=6\\\\3x=6\\\\x=\frac{6}{3} \\\\\therefore x =2

Now Substituting x = 2 in Equation ( 1 ) we get

y =2\times 2\\\\\therefore y=4

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

7. for normal situations, the minimum speed limit throughout the u.s. interstate highway system is 72 km/hr which is 45 miles pe
gladu [14]

Answer:

Question 7: Distance = 237.6 km

Question 8: Distance = 399.3 km

Step-by-step explanation:

Question 7:

Given:

Minimum speed (s) = 72 km/hr

Time taken (t) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Minimum speed × Time

Distance = s\times t

Distance = 72\times 3.3 = 237.6\ km

Therefore, distance traveled at this speed is 237.6 km.

Question 8:

Maximum speed (S) = 121 km/hr

Time taken (T) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Maximum speed × Time

Distance = S\times T

Distance = 121\times 3.3 = 399.3\ km

Therefore, distance traveled at this speed is 399.3 km.
