Answer: 55 degrees
Step-by-step explanation:
180-125=55
125 and m make a half a turn which equals 180
b - 10 = 7
Take 10 to the other side.
b = 17
Multiply by 4 to isolate b
b × 4 = 17 × 4
4 and 4 cancels out
b = 68
Answer:
x=0 or f square root of 3f/9 or -f square root of 3f/9
Step-by-step explanation:
the steps are very long but I'm pretty sure it's correct
Answer:
(10x + 8) is the polynomial expression for the perimeter of the blanket.
Step-by-step explanation:
The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.
Now, the perimeter of a rectangle having height h and width w is given by
P = 2h + 2w
⇒ P = 2(2x - 3) + 2(3x + 7)
⇒ P = 4x - 6 + 6x + 14
⇒ P = 10x + 8.
So, this is the polynomial expression for the perimeter of the blanket. (Answer)
