sorry but where is Elisa's explanation???
Let width of rectangle be "x"
L= 3x W=x
if width is diminished by 1 that means new width = (x-1)
similarly the new length would be (3x+3)
hence (x-1)*(3x+3)=72
(3x^2)-3=72
3x^2=75
x^2=25
x= +/- 5
reject -5 as you cant have negative length
hence x=5
so original dimensions of rectangle is
L= 15m W=5m
Answer:
10%
Step-by-step explanation:
Samantha is a business development representative
She took her client out for a dinner that costs $180.75 before taxes
She paid tax of $18.08 on the meal
The tax rate can be calculated as follows
= 18.08/180.75
= 0.1 ×100
= 10%
Hence the tax rate is 10%
B
the surface area (SA ) is made up of 2 rectangles 2 by 6, 2 rectangles 2 by 5 and 2 rectangles 6 by 5
SA = 2( 2 × 6 ) + 2(2 × 5 ) + 2(6 × 5 )
= 24 + 20 + 60 = 104 m²
