Answer:

G, the second option

Step-by-step explanation:

A triangle's degrees all adds up to 180.

45 + 60= 105 degrees

180-105= 75 degrees

that in which makes z=75 degrees.

Since z is sharing a straight angle, which is 180 degrees

180-75= 105 degrees.

Therefore, w=105 degrees

Solve the following system of equations and show all work. y = −x2 + 4 y = 2x + 1

Aneli [31]

Answer:

x=3/4,y=5/2

Step-by-step explanation:

y=-x^2+4,y=2x+1

substitute y=-x^2+4 as y for y=2x+1

2x+1=-x^2+4, x=3/4(isolate "x")

x=3/4

substitute x=3/4 for 2x+1=-x^2+4

y=2*3/4+1

y=5/2

x=3/4, y=5/2

hope this helps!

How to sovle (x+1/x)^2

Slav-nsk [51]

$(\frac{x + 1}{x} ) ^{2} \\ = \frac{ {(x + 1)}^{2} }{ {x}^{2} } \\ = \frac{ (x + 1)(x + 1) }{ {x}^{2} } \\ = \frac{ {x}^{2} + 2x + 1}{ {x}^{2} }$

Hope you could get an idea from here.

Pls help and explain

grin007 [14]

Answer:

Step-by-step explanation:

First distribute the 2x to get:

4x² + 10x

Then distribute the -5 to get:

-10x - 25

Then combine

4x² + 10x - 10x - 25

The 10x's will cancel leaving you:

4x² - 25
