So since the length is 4+w. Then the perimeter 2(4+w) + 2w >= 48.
so, 8+2w+2w>=48.
8+4w>=48
4w>=40
w>=10
so, the width must be at least 10. And the smallest dimensions can be 10 x 14.
Answer:
No, Dolly won't have enough money to buy the bracelet.
Step-by-step explanation:
30-25=5
5<10
(a)
A right angle sums to 90
6x + 4x + 10 = 90
10 x = 80
x = 8
(b) straight line = 180
5x + 13 + 3x + 7 = 180
x = 20
(c) Sum of triangle angles = 180
3x + 5 + 2x + 18 + 2x + 17 = 180
x = 20
(d) Sum of two angles in right angle = 90
90 = x + 30
x = 60
C is what I think/Know for sure
