The red triangle and the green rectangle are 14
The purple triangle and blue square are 16
Triangle is
(1/2)*Base*Height
Answer:
BC ≈ 14 units
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
BC² + AB² = AC²
BC² + 18² = 23²
BC² + 324 = 529 ( subtract 324 from both sides )
BC² = 205 ( take square root of both sides )
BC = 
= 14.317.. ≈ 14 units ( to the nearest unit )
97 - 68 = 29
Bill ran 29 more yards than Matt (0.29)
Answer:
53
Step-by-step explanation:
If Max spent $53 and currently doesn't have anything left that means he had $53 before he made his purchase.
|6x + 5| = 7 · 3
|6x + 5| = 21
6x + 5 = 21 (1st equation)
-6x + 5 = 21
(1st equation)
6x = 21 - 5
6x = 16
x = 8/3
(2nd equation)
-6x - 5 = 21
-6x = 21 + 5
-6x = 26
x = -13/3
so all of the solutions are;
x = -13/3, 8/3
