Question

Please help me once more! I only need the answer to D. The value of x is 10.

Answer 1

Length=21, width=15. to find these answers, you would replace x with 10, which leads to 2(10)+1 for length and 10+5 for width. then you would multiply 2 with 10 and add 1, giving you 21, and add 10 with 5, giving you 15
