Answer:
122.5 units
Step-by-step explanation:
The perimeter of Figure B is the sum of its side lengths:
12 + 9 + 5 + 9 = 35
The perimeter of Figure A is that value multiplied by the scale factor:
(7/2)(35 units) = 122.5 units
Answer:
three and four tenths
Step-by-step explanation:
Answer:
X=10
X=-8
Step-by-step explanation:
(x+1)*(x-3)=77
x²-3x+x-3=77
x²-2x-3=77
x²-2x-3-77=0
x²-2x-80=0
(x-10)*(x+8)=0
x-10 = 0
x=10
x+8=0
X=-8

Answer:
The answer is 350.
Step-by-step explanation:
The joint variation of W with x, y and z may be expressed as follow, W = kxy / z²where k is the constant of variation. Substituting the first set of values for the variables, 280 = k(30)(12) / 3²The value of k from the equation is 7. Substituting to the same equation the values of the next set of variables, w = (7)(20)(10) / 2² = 350
