Answer:
- 21x -28y
- 30 minutes
Step-by-step explanation:
1. The distributive property tells you the factor outside parentheses multiplies each of the term inside parentheses.
7(3x -4y) = 7·3x -7·4y = 21x -28y
__
2. Time, speed, and distance are related by ...
time = distance/speed
time = (20 mi)/(40 mi/h) = 1/2 h = 30 minutes
The drive takes 30 minutes.
2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer

Step-by-step explanation:
Answer:
200
Step-by-step explanation:
the formula for working out the area is to multiply the length by the width.
so for this you would multiply 100 by 2 which gives you 200 cm squared
Um, is there angles to look at, or an actual problem?
