Answer: 8(x+5) 8x + 40
40 + 8x
Step-by-step explanation:
Distribute the 8 by multiplying by each value inside the parentheses.
Commutative property in addition and multiplication allows the terms to be in reversed order.
It takes 2.8 hours for Max to cover the same route by walking with 3 mph. The certain route has 8.4 miles distance which can be acquired by multiplying the velocity and the amount of time (3.5 x 2.4). Then the new amount of time can be acquired by dividing the certain route distance by the new velocity (8.4 / 3). All of the calculations above are calculated with the basic formula of constant velocity which is velocity = change of position/change of time.
Answer:
Model 1 represents 85% shaded area.
Step-by-step explanation:
Here, each model consists of equal sized rectangles.
Please refer to attached figure to know the model number.
Model 2 (on top right of question figure) contains a total of 20 such rectangles out of which 13 are shaded. As per formula of percentage:

Model 3 (on bottom left of question figure) contains a total of 16 such rectangles out of which 10 are shaded. As per formula of percentage:

Model 4 (on bottom right of question figure) contains a total of 16 such rectangles out of which 13 are shaded. As per formula of percentage:

Model 1 (on top left of question figure) contains a total of 20 such rectangles out of which 17 are shaded. As per formula of percentage:

Hence, model 1 is the correct answer.
