Answer:
4.5 I hope I was not to late
X = 19
Because it’s an isosceles triangle, those two sides have to equal to each other so
2x+ 7 = 45
Subtract 7 from both sides
2x = 38
Divide by 2
X = 19
4/26 can be simplified by 2. So, this is not the answer.
8/21 cannot be simplified. So, it is one of the answers.
6/19 cannot be simplified. So, it is one of the answers.
9/10 cannot be simplified. So, it is one of the answers.
10/22 can be simplified by 2. So, this is not the answer.
So, the fractions in simplest forms are 8/21, 6/19, and 9/10.
The room is 15yd × 10yd
so 15×10=150
the room is 150 square ft
First do 70+24=94
Then do 180-94=86
Next 86+54=140
Then 180-140=40
Next 40+80=120
Lastly 180-120=60
X=60
