Answer:
c
Step-by-step explanation:
you have to find the surface area of all sides. so (11*11)*2 and (11*9) *4 with this you get c. 638in square.
All you needed to do was plug in 5 into C
Answer:
This is in Tajik language which means :
- The farm has fifteen cows. increases twice a year. How many cows will there be in seven years?
Answer: 5,975,000
Steps: (7.5 × 10⁴) + (5.9 × 10⁶)
7.5 × 10⁴ = 75,000
5.9 × 10⁶ = 5,900,000
75,000 + 5,900,000 = 5,975,000
Plz mark brainliest:)
Let the increase be x m
new length=(7+x)m
new width=(4+x) m
the current area of the garden is:
Area=length*width
A=4*7=28 sq. meters
when the area is doubled we shall have:
28*2=56
thus the new area will be:
(x+7)(x+4)=56
x^2+11x+28=56
x^2+11x-28=0
solving for x we get:
x=2.1
thus the dimensions are:
length=7+2.1=9.1
width=4+2.1=6.1
