Answer:
The correct answer is x = 17.
Step-by-step explanation:
If EF bisects DEG, this means that angles DEF and angles FEG are congruent, and they each make up half of angle DEG.
Therefore, we can set up the equation:
DEF + FEG = DEG
However, since we know that DEF and FEG represent the same value, we can change this equation into the following:
2(DEF) = DEG
Now, we can substitute in the expressions that we are given:
2(3x+1) = 5x + 19
To simplify, we should first use the distributive property on the left side of the equation.
6x + 2 = 5x + 19
Our next step is to subtract 5x from both sides of the equation.
x + 2 = 19
Finally, we can subtract 2 from both sides of the equation to get x by itself on the left side.
x = 17
Therefore, the value of x is 17.
Hope this helps!

Answer:
5 + 4 - (8 * 3 - 22)⁴ * 4 = -55
Step-by-step explanation:
5 + 4 - (8 * 3 - 22)⁴ * 4
Follow PEMDAS which states you need to do equations in the order of:
Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Knowing this, simplify inside the parenthesis by multiplying 8 and 3 first.
5 + 4 - (24 - 22)⁴ * 4
Now subtract 22 from 24 inside the parenthesis.
5 + 4 - (2)⁴ * 4
Since we are done with parenthesis, move on to the next part of PEMDAS which says to do exponents next. Take 2 to the power of 4.
5 + 4 - 16 * 4
Now that we are done with exponents, move on to the next part of PEMDAS which says to multiply/divide next. Multiply -16 and 4.
5 + 4 - 64
Now that we are done with multiplication/division, move on to the last part of PEMDAS which says to add/subtract. Add 5 and 4.
9 - 64
Finally, subtract 64 from 9 to get:
-55.
