If it is area you're looking for, the answer is 7.92 cm^2, or ~7 11/12 cm^2.
The best answer for this question would be:
D. 32
In order to get this, you have to get the sum in the line,
which is the first four people. So the solution would be: 4(23) = 92
For getting the sum of the people in the last 3 would be:
3(34) = 102
Next is the sum of everyone which the solution would be:
6(27) = 162
So the initial solution that we have now would be: F + 92 -
F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
The (F) here or the fourth person’s age would be= -32 / - 1
or 32
Answer
x= 3 and 7
Step-by-step explanation:
√4x-3 - √2x-5=2
√4x-3=2+√2x-5
squaring both sides
(√4x-3)²=(2+√2x-5)²
4x-3=2²+2*2*(√2x-5)+(√2x-5)²
4x-3=4+4(√2x-5)+2x-5
4x-2x-3+5-4=4(√2x-5)
2x-2=4(√2x-5)
again squaring both sides
(2x-2)²=(4(√2x-5))²
(2x)²-2*2x*2+2²=16(2x-5)
4x²-8x+4=32x-80
4x²-8x-32x+4+80=0
4x²-40x+84=0
4(x²-10x+21)=0
x²-10x+21=0
x²-(7+3)x+21=0
x²-7x-3x+21=0
x(x-7)-3(x-7)=0
(x-7)(x-3)=0
now
x-7=0
x=7
x-3=0
x=3
