Answer:
π + 2
Step-by-step explanation:
x² + y² - 4x - 4y + 4 = 0
(x² - 4x + 4) + (y² - 4y + 4) + 4 - 4 - 4 = 0
(x - 2)² + (y - 2)² = 4
So the radius of the circle = 2, center C(2, 2)
Are a of AMNB = area of semi-circle - area of segment AB
= area of semi-circle - (area of quarter circle ABC - area of triangle ABC)
= area of quarter circle ABC + area of triangle ABC
= π(2)²/4 + 2*2/2
= π + 2
Answer:
Width = 7 units
Step-by-step explanation:
Length = x units
Width = (x -1) units
Area = 56 square units
length * width = 56
x * (x - 1) = 56
x*x - x*1 = 56
x² - x - 56 = 0
x² -8x + 7x - 7*8 = 0
x(x - 8) + 7(x - 8) = 0
(x - 8)(x + 7) = 0
Here, (x +7) is ignored because measurement will not in negative.
x - 8 = 0
x = 8
Length = 8 units
Width = 8-1 = 7 units
Width
Answer:
Erica: 20
Bo:15
Step-by-step explanation:
(2x - 10) + x =35
3x-10=35
3x=35+10
3x=45
x=15
2x-10=30-10
30-10=20
Answer:
3.8
Step-by-step explanation:
.8 is in the tenths
Answer:
(1, 1)
Step-by-step explanation:
if you do not want to graph it then you can substitute 'x' and 'y' values and check:
does 2(5) + 3(5) equal 5? NO
does 2(1) + 3(2) equal 5? NO
does 2(1) + 3(1) equal 5? YES
does 2(2) + 3(5) equal 5? NO
