We know that
[perimeter of rectangle]=2*[length+width]
length=(2x-7)
width=(x²-5)
[perimeter of rectangle]=2*[(2x-7)+(x²-5)]----> 2*[x²+2x-12]---> 2x²+4x-24 in
the answer is
(2x²+4x-24) in
Answer:
50%
Step-by-step explanation:
0.3x = 15
0.3x x 10 = 15 x 10
3x = 150
3x/3 = 150/3
x = 50

Step-by-step explanation:
Answer:
3. 102
4. c
Step-by-step explanation:
For number 3:
(c^2 - a) + b becomes (10^2 - 3) + 5
10^2 = 100
100 - 3 + 5 = 102
For number 4:
Usually when you see distributive property, you're multiplying into parentheses. This time you're factoring out.
20c - 8d
It's not a, because that would be 20c + 8d
It's not b, because that would be 20c -32d
It is c, because 4 x 5c = 20 c and 4 x -2d = -8d
It's not d, because that would be 20c- 8cd
