Answer:
A = 6x² + 97x + 391
Step-by-step explanation:
Given that,
The length of the shop, l = (3x+23)
The width of the shop, b = (2x+17)
The expression for the area of the shop is given by :
A = lb
Put all the values,
A = (3x+23) × (2x+17)
= 6x² +51x+46x +391
= 6x² + 97x + 391
Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.
Step-by-step explanation:
T = beads of Ting Ting = 165
S = beads of Sherie.
R = beads of Roxanne.
S = 4/5 × T = 4/5 × 165 = 4 × 33 = 132 beads
R = 1/2 × S = 1/2 × 132 = 66 beads
Ting Ting has therefore 165 - 66 = 99 more beads than Roxanne.
Answer:
2 - x
Step-by-step explanation:
Add together any numbers that need to be together
5 - 2x - 3 + x
2 - x
