Answer:
3. x = 10
4. a = 8
Step-by-step explanation:
A reasonably simple rule to remember for secants outside the circle or chords inside the circle: the product of the lengths from the point of intersection of the lines to the points of intersection of the circle is the same for each line.
When the external line is tangent to the circle, the two points of intersection of the line with the circle are the same: the point of tangency. Effectively, this means the length is squared.
__
3. For line QP, the product is 3(3+5) = 24.
For line QR, the product is 2(2+x). The rule above says these are equal:
24 = 2(2+x)
12 = 2+x . . . . . divide by 2
10 = x . . . . . . . subtract 2
__
4. For line BC, the product is (a)(a) = a^2.
For line GC, the product is 4(12+4) = 64. The rule above says these are equal:
a^2 = 64
a = √64 . . . . take the square root
a = 8

Can somebody help me with this problem 22/35+35x3
Answers
22/35+35x3
Division comes first.
22/35=0.62857142857 or just 0.629, or 0.63
0.63+35x3
Now we multiply.
35x3=105
So now we have 0.63+105.
Lastly, we add.
0.63+105=105.63
The answer is 105.63.

The factors of 12 are 1, 2, 3, 4, 6, 12
The factors of 88 are 1, 2, 4, 8, 11, 22, 44, 88.
So, as we can see, the Greatest Common Factor or Divisor is 4, because it is the greatest number that divides evenly into all of them.

Answer:
(b) -15
Step-by-step explanation:
The area under the curve from -5 to +5 can be divided into two trapezoids. The one from x=-5 to x=1 has an area of ...
A = 1/2(b1 +b2)h = 1/2(1 +6)(5) = 17.5
The one from x=1 to x=5 has an area of ...
A = 1/2(4 +3)(-1) = -3.5
So, the total area from x=-5 to x=+5 is 17.5 -3.5 = 14. This is the amount by which f(x) increases from f(-5) to f(5). That is ...
f(-5) +14 = -1
f(-5) = -15
