Answer:
The correct answer is 8x^2+28x+20.
Step-by-step explanation:
(2x+5)(4x+4)
Multiply the first bracket with each element of second bracket:
=4x(2x+5)+4(2x+5)
=8x^2+20x+8x+20
Now solve the like terms:
=8x^2+28x+20
Thus the correct answer is 8x^2+28x+20....
Answer:
yeas they are the same shape just different sizes
Step-by-step explanation:
The answer is c because if you have a square and you look at a reflection you can see that a square has 4 sides so if you look at the reflection you would see another of the square. So what you would do is 4+4 which equals to 8.
Since the first equation says y= x-4, substitution that for the y value in x + y = 6
x + x - 4 = 6
add up the x’s to get 2x - 4 = 6
add 4 to both sides to get 2x = 10
divide both sides by 2 to get x = 5
the x value is 5
then, to figure out the y value, substitute 5 for the x value in y = 5-4
the y value is 1
final answer: x = 5 and y = 1
