Z = 79° (supplementary to 109°) and y = 102° (all angles of a quadrilateral add to 360, so do 360-96-83-79 to get 102°)

Solve for x.<br> I was sure the answer was 2?<br> Please show me the breakdown. THX

Murljashka [212]

Answer:

x = 8 and y = 10

Step-by-step explanation:

Since the figures are congruent:

Angle PQR = EFG

6y + x = 68

Segment QR = FG

2x - 4 = 12

Solving that:

2x - 4 = 12

2x = 16

x = 8

Replacing x in 6y + x =68

6y + 8 = 68

6y = 60

y = 10

Four students are trying to determine what number must replace the question (x^2)^7=x^4*x^8 in order to make it true

tiny-mole [99]

Answer:

Joe is correct

Step-by-step explanation:

Given equation:

$(x^2)^?=x^4 \cdot x^8$

The exponent outside the bracket is a question mark and the students are trying to determine the value of the question mark.

For ease of answering, let y be the unknown number (question mark):

$\implies (x^2)^y=x^4 \cdot x^8$

First, simplify the equation by applying exponent rules to either side of the equation:

$\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}\quad\textsf{to the left side}:$

$\implies (x^2)^y=x^4 \cdot x^8$

$\implies x^{2y}=x^4 \cdot x^8$

$\textsf{Apply exponent rule} \quad a^b \cdot a^c=a^{b+c} \quad \textsf{to the right side}:$

$\implies x^{2y}=x^4 \cdot x^8$

$\implies x^{2y}=x^{4+8}$

$\implies x^{2y}=x^{12}$

Now, apply the exponent rule:

$x^{f(x)}=x^{g(x)} \implies f(x)=g(x)$

Therefore,

$x^{2y}=x^{12}\implies 2y=12$

Finally, solve for y:

$\implies 2y=12$

$\implies 2y \div 2 = 12 \div 2$

$\implies y=6$

Therefore, <u>Joe is correct</u> as the unknown number is 6.
