5(2x - 4)
10x - 20
10x - 20 = 0
10x = 20
x = 2
Answer:
-64
Step-by-step explanation:
y = -3 (23) + 5
y = -69 + 5
y = -64
Answer:
3.4 + 3.4 = 6.8
Step-by-step explanation:
Review your triangle and geometry. Since the triangles are both similar, they would have the same side.. etc.
Answer:
65.8 ft
Step-by-step explanation:
The number of strings required to tie each vertex to the other three will be ...
(4)(3)/2 = 6
Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.
d² = 12² +7² = 144 +49 = 193
d = √193 ≈ 13.892
Then the total length of all strings is ...
L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet
The artist will need 65.8 feet of string.
