What are the demensions of a rectangle if the perimiter is 20 and the area is 24
1 answer:
Answer:
I simply listed the factors of 24, and tested which ones worked in this equation: P = 2a + 2b.
So the factors listed were:
24 x 1
12 x 2
8 x 3
6 x 4
After testing each one of these, 6 and 4 had worked for me.
P = 2(6) + 2(4)
P = 12 + 8
P = 20
Therefore, the dimensions of this rectangle are 6 and 4.

Answer:
f(5) = 44
Step-by-step explanation:
f(x) = 3|x+11| -4
let x =5
f(5) = 3|5+11| -4
= 3|16| -4
= 3*16 -4
= 48 -4
= 44
Answer:
Hence the expression 
Step-by-step explanation:
Explanation
- The given expression is (m+11)(m-4).
- We have to multiply the given expression.
- Multiply the (m+11) by -4, multiply the (m+11) by m then add like terms.
