Step-by-step explanation:
number2 the answer is a and
number 3 the answer is letter b
Answer:
w=22
Step-by-step explanation:
5(w-2)+10=3(2w-9)+5
1) Use the Distributive Property for 5(w-2) and 3(2w-9):
5w-10+10=6w-27+5
2) Combine alike terms:
5w=6w-22
3) Add a 22 to both sides:
22+5w=6w
4)Subtract 5w from both sides:
w=22
Answer:
9x^2-25
Step-by-step explanation:
You can solve this problem by using FOIL:
- FOIL (First, Outer, Inner, Last)
First: 3x*3x= 9x^2
Outer: 3x*-5= -15x
Inner: 3x*5 = 15x
Last: 5*-5= -25
Now add what we got together:
9x^2 -15x +15x -25
Answer: 9x^2 - 25
Note: Whenever when we see conjugates(coefficients of variables are same but real numbers are opposites) like these we can ignore the outer and inner of the foil process as they cancel out.
Hope this helps!
Answer:
PS = 84.5 , x = 43.75
Step-by-step explanation:
Since RQ is congruent to PS, PS is 2x - 3
SR: 4x + 1
Extra at the bottom: 4
4x + 1 + 4 = 180
4x + 5 = 180
- 5 - 5
4x = 175
/4 /4
x = 43.75
Plug in for PS
2 (43.75) - 3
87.5 - 3
84.5
I hope this helps!
