I need help solving these two questions For question 4 it also isn't D
For question 7 it also isn't B

i could be A and the next one is c

Step-by-step explanation:

First question 8

Second question 10

Step-by-step explanation:

First question

The general formula for both secants is the entire length * the external segment.

Using an example, it is 3*(13 + 3) = 3*16

The other secant will be 4*(x + 4)

These two are equal

4(x + 4) = 3 * 16

4(x + 4) = 48                Divide by 4

x + 4 = 12                    Subtract 4 from both sides

x = 8

Second Question

8(x + 8) = 6(6 + 18)

8x + 64 = 6(24)

8x + 64 = 144            Subtract 64

8x = 80                     Divide by 8

x = 80 /8

x = 10

1)when subtracting an integer is the same as answeradding its opposite2) the result of subtracting 2 from its opposite is -4cause -2 - 2 = -4answer-43) the distance between -18 and 15 is equal to answer15 - (-18)4) what is the change in temperature from -45°f to - 71°f? 26°f5) find the value of -7 - 8 - (-8) - 7.= -7 - 8 + 8 - 7 = -14answer=-146) find the value of -9 - 6 - (-8).= -9-6 + 8= -7answer-77) what is the change in elevation from 134 feet below sea level to 29 feet above sea level? -134 + 29 = -105answer-105 feet8) what is the change in temperature from 15° to -9°? 15 - (-9) = 24answer24°9) a company has a monthly profit, or gain, of $6,400. the next month they have a loss of $4,700.what expression would you use to find the difference in profit between the two months? answer6400 - 4700  10) how many degrees warmer is a temperature of 13°f than a temperature of -19°f? answer32°f11) subtracting a negative number is the same as answeradding a positive number
