Answer:

x = 6

Step-by-step explanation:

Looking at the figure, we can say that it is a vertical angle.

5x - 7 = 23

5x - 7 + 7 = 23 + 7

5x = 30

5x / 5 = 30 / 5

x = 6

Since it is a vertical angle, the other side should be 23⁰. You can also plug in the x value to find if it gives you 23⁰ or not.

5x - 7

5(6) - 7

30 - 7

Therefore, x = 6. Hope this helps and stay safe, happy, and healthy, thank you :) !!

X^2+2x+1 is a perfect square trinomial True of False?

Nimfa-mama [501]

Answer:

True.

Step-by-step explanation:

It is because it is in the form $a^2x^2+2abx+b^2$ and this equals $(ax+b)^2$ .

Why it is in that form: well comparing $a^2x^2+2abx+b^2$ , we have $a=1, b=1$ . Testing, plug in those values:

$(1)^2x^2+2(1)(1)x+(1)^2$

$1x^2+2x+1$

$x^2+2x+1$ .

This has the squared form of $(x+1)^2$ .

Test if you like:

$(x+1)^2$

$(x+1)(x+1)$

Use foil to expand:

First: x(x)=x^2

Outer: x(1)=x

Inner: 1(x)=x

Last: 1(1)=1

---------------Add together

$x^2+2x+1$

It does indeed equal.
