Answer:
13 Compute using the 2 right angles, we know that m<FIG=90* and
TWENTY FIVE TWENTY SIX that’s my answer I hope this help
The aim here is to get all of the x's onto one side and the numbers onto the other side:
We can start by subtracting x from each side
2x+11=1
We can then subtract 11 from both sides
2x=-10
Finally, we can divide both sides by 2 leaving us with:
x = -5
2x2 +3x -7 =x2 +5x +39
2x2 +3x -7 -x2 -5x -39=0
x2 - 2x -46 =0
(x-1)2 -46 -1 =0
(x-1)2 -47=0
(x-1)2 = 47
x-1= + or - the square root of 47
x= 1 + or - the square root of 47
Answer:
circumference (c) = 43.96cm
Area (A) = 615.44cm²
Step-by-step explanation:
Here,
Radious (r) = 7 cm
circumference (c) = ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
= 2×3.14×7
=43.96cm
Area (A) = ![4\pi r^{2}](https://tex.z-dn.net/?f=4%5Cpi%20r%5E%7B2%7D)
= 4×3.14×7²
=12.56×49
= 615.44cm²
