Answer:
25
Step-by-step explanation:
Using the rules of BIDMAS, you first work out the calculation inside the bracket. y-z equals 25-20 which equals 5. then, you work out out the fraction. x=10 so 10/2 equals 5. Then, multiply the value inside the bracket (5) by the outside value(5). This equals 25
Step-by-step explanation:
it would be 45 if you add it as 21 but you didn't put another symbol hope I can help :)
Answer:
t^2 - 11t + 14
Step-by-step explanation:
Begin by grouping like terms in 9t^2+14-17t+6t-8t^2.
First we have 9t^2 - 8t^2, or 1t^2.
Next, we have -17t + 6t, or -11t.
Last, we have the constant term 14.
The expression in simplified form is t^2 - 11t + 14.
The answer to your question is “D”
Btw you can use DESMOS for future questions like this
The fraction 8/21 cannot be simplified because the numerator and denominator don't have a common factor except 1.
