Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.
Answer:
C and D
Step-by-step explanation:
::::
b= 4/11 , b= - 4/11
To solve this, you need to isolate/get the variable "n" by itself in the equation:
132 = 3(5n + 4) First divide 3 on both sides
![\frac{132}{3}=\frac{3(5n+4)}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B132%7D%7B3%7D%3D%5Cfrac%7B3%285n%2B4%29%7D%7B3%7D)
44 = 5n + 4 Subtract 4 on both sides
44 - 4 = 5n + 4 - 4
40 = 5n Divide 5 on both sides to get "n" by itself
![\frac{40}{5} =\frac{5n}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B5%7D%20%3D%5Cfrac%7B5n%7D%7B5%7D)
8 = n
PROOF
132 = 3(5n + 4) Substitute/plug in 8 into "n" since n = 8
132 = 3(5(8)+4)
132 = 3(40 + 4)
132 = 3(44)
132 = 132
