Answer:
length and width of the photo are: w = 6cm l = 8cm
Step-by-step explanation:
Area = 168cm^2
Area = w • l
168 = (x + 3 + 3) • (x + 2 + 3 + 3)
168 = (x + 6) • (x + 8)
expand
168 = x^2 + 14x + 48
subtract 168 from both sides
0 = x^2 + 14x - 120
simplify
0 = (x - 6) • (x + 20)
x = 6 or -20
since we are dealing with a measurement of a physical object x > 0
x = 6cm
w = x = 6cm
l = x+2 = 8cm
Babel of an this is the answer
Answer:
N = 15 & x = 3.2
Step-by-step explanation:
divide 6 by 2 to get 1/5, which is 3. then you multiply 3 by 5 to get the answer.
sixteen-thirds is equal to 5 1/3, which you can divide by 7 to get one-seventh, which is 0.8. Then you can multiply that by 4 to get 3.2.
Answer:
ans is C. 63 ft.
Step-by-step explanation:
u, tree base n tree top form a right-angle triangle w/
an angle of 49deg
adjacent side = 55'
opposite side = tree height
using trig fn tan(angle)=opposite/adjacent
tan(49deg)=tree height/55'
tree height=55'*tan(49deg)
=63.27' rounding to 63 ft.
Basically, we are to find the area of the television screen. Because a TV is rectangular in form, the formula for the area is written below:
A = L×W
The given dimensions are 64 inches in length and 52 inches in width. But that includes the edges. To compute for the screen area only, we subtract 4 inches (2 inches on both sides) to each dimension.
A = (64 - 2)(52 - 2)
A = 3,100 square inches
