The given expression is :
2xx+3-5(x-2)
We know that, 
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
The high temperature was 35 degrees warmer than the low temperature.
Answer:
A
Step-by-step explanation:
Answer:
20 + 10 = blank × (4 + 2)
30 = blank × 6
blank = 30 ÷ 6 = 5
Answer:
I believe X = 8
Step-by-step explanation:
you would use the equation D + C = B or
48 + 5x + 11 = 11x + 11
then subtract 11 from each side leaving
48 + 5x = 11x
then you would subtract 5x from each side, leading to
48 = 6x
48 ÷ 6 = <u>8</u>
