So we know that the sum of angle of a triangle is equal 180 degree
than there are 10x-1 +35 +15x+4 = 180
10x +15x = 180 -38
25x = 142
x = 142/25
x = 5,68

Answer:
360,000.
Step-by-step explanation:
9! - 4! (5!)
= 9*8*7*6*5*4*3*2*1 - 4*3*2*1 * 5*4*3*2*1
= 5*4*3*2*1 ( 9*8*7*6 - 4*3*2*1)
= 120( 3024 - 24)
= 120 * 3000
= 360,000
Answer:
x = ± 3, x = ± 2i
Step-by-step explanation:
Given
f(x) = (x² + 4)(x² - 9)
To find the zeros let f(x) = 0, that is
(x² + 4)(x² - 9) = 0
Equate each factor to zero and solve for x
x² - 9 = 0 ( add 9 to both sides )
x² = 9 ( take the square root of both sides )
x = ± = ± 3
x² + 4 = 0 ( subtract 4 from both sides )
x² = - 4 ( take the square root of both sides )
x = ± = ± = ± × = ± 2i
Thus zeros are
x = - 3, x = 3 ← real
x = - 2i, x = 2i ← complex
Answer: $21, 600
Step-by-step explanation:
Given:
Original cost (when the shop owner brought it) = $20,000
Profit amount = 20% of original cost
Discount rate = 10%
Solve:
First Step: Find the market price (before discount)
- $20, 000 × (1 + 20%) = $24, 000
Second Step: Find the discount price
- $24, 000 × (1 - 10%) = $21, 600
Hope this helps!! :)
