5(7 + 23) because you are multiplying 7 + 23 by 5. This is a numerical expression because it has numbers and opperations. This is not an algebraic expression because there are NO variables. Hope this helps :)
Answer:
27.2 ft
Step-by-step explanation:
We solve using the Trigonometric function of tan
tan θ = Opposite/Adjacent
θ = 66°
Opposite = Height of the building = 61 ft
Adjacent = Length of the shadow = ? = x
tan 66 = 61/x
Cross Multiply
tan 66 × x = 61
x = 61 ft/tan 66
x = 27.158949804 ft
Approximately = 27.2 ft
The length of the shadow = 27.2 ft
Number is n
Three times the sum of a number and 4.
= 3* ( n + 4) = 18
3n + 12 = 18.
3n = 18 - 12.
3n = 6
n = 6 / 3.
n = 2.
Answer:
The value of x is 13°
Step-by-step explanation:
<u>Given:</u> m || n
For a straight line = 180°
Now, by exterior angle
(7x - 1)° + (8x - 14)° = 180°
7x - 1° + 8x - 14° = 180°
15x - 15° = 180°
Now, add 15° both side we get,
15x - 15° + 15° = 180° + 15°
15x = 195°
Now, divide both side by 15
15x/15 = 195°/15
x = 13°
Thus, The value of x is 13°

I'm not sure. But i think the answer is C
You can see that none of the lines are about to/ are intersecting
