Answer:
4
Step-by-step explanation:
11 - 7 = 4
Answer: 8 units
Step-by-step explanation:
Set this up as an equation with a variable for turtles. Count up the other side of the scale (without turtles). Add up the three 1s and the 4 to get 7. Then add up all four 7s. This will get you with an equation 3t+4=28.
To solve this, first subtract 4 from both sides to get 3t=24. Now divide both sides by 3. 24/3=8. Each turtle weighs 8 units.
Answer:
=7x^2−28
Step-by-step explanation:
Let's simplify step-by-step.
7(x−2)2+28(x−2)
Distribute:
=7x2+−28x+28+(28)(x)+(28)(−2)
=7x2+−28x+28+28x+−56
Combine Like Terms:
=7x2+−28x+28+28x+−56
=(7x2)+(−28x+28x)+(28+−56)
=7x2+−28
Answer:
