Answer:
Step-by-step explanation:
<u>You need to find the difference:</u>
- 17.50x + 25 - (8.50x + 3) =
- 17.50x - 8.50x + 25 - 3 =
- 9x + 22
Correct one is B
Answer:
<u>f(g(x)) = 9x² + 15x + 2</u>
Step-by-step explanation:
- f(x) = x² + 5x + 2
- g(x) = 3x
<u>Solving f(g(x))</u>
- f(g(x))
- f(3x)
- f(3x) = (3x)² + 5(3x) + 2
- f(3x) = 9x² + 15x + 2
- <u>f(g(x)) = 9x² + 15x + 2</u>
Answer:
{15 - {(25 x 2.4) + 7}}- (3 x 2) = -16
Step-by-step explanation:
15 - 25 x 2.4 + 7 - 3 x 2= -16 is the given equation.
Now by the rule of BODMAS:
here B = Bracket, O means Of, D means Divide, M means Multiplication , A means Addition and S means Subtraction.
So, according to this order start putting brackets.
first operation is multiplication, second is addition and then subtraction.
⇒ 15 - 25 x 2.4 + 7 - 3 x 2 = {15 - {(25 x 2.4) + 7}}- (3 x 2)
Hence, {15 - {(25 x 2.4) + 7}}- (3 x 2) = -16
Answer:
90:55
Step-by-step explanation:
18 + 11 = 29
145/29 = 5
5 x 18 = 90
5 x 11 = 55
