For each expression,use a property to write an equivalent expression.Tell which property you used.
10:CD=
11:x+13=
12:4(2x-3)=
1
3:2+(a+b)=
14:Draw algebra time models to prove that 4+8x and 4(2x+1) are equivalent.
1 answer:
10.) DC
community property
11.) 13+x
community property
12.) 8x-12
distributive property
13.) (2+a)+b
14.) 4(2x+1)= 4+8x
For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)

Answer:
300 squared feet.
Step-by-step explanation:
Area of a rectangle = length × breadth = 20 × 15 = 300 squared feet.
To do this we take the outlier off the parenthesis (the 4) and multiply it by the two numbers inside the parenthesis...
4*7 + 4*8
28+32
(1,4) this is because the flip over y axis does not touch the y value but gives the opposite of the x value
You also need to brake down this answer farther.
