= 90°/2
= 45°
x = 45° - 16°
x = 29°
y = 45° + 16°
y = 61°
61° and 29° i guess.
Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)
Answer:
SI = $810
Amount = $3,810
Step-by-step explanation:
Given that ,
- P = $ 3,000
- R = 5.4%
- T = 5 yrs .
We can use the formula of SI to find the interest as ,
=> SI = P × R × T / 100
=> SI = $ 3000 × 5.4 × 5 / 100
=> SI = $ 30 × 5.4 × 5
=> SI = $ 810 .
- If you want to know total amount , then ,
=> Amount = SI + P
=> Amount = $ 810 + $ 3,000
=> Amount = $ 3,810
