Only A
And only when x = 1

Nothing else works.

Think About a Plan Write an indirect proof.

1) Either $\ell \parallel p$ or $\ell$ ∦ $p$ (only two possibilities)

2) Assume $\ell \parallel p$ (one of two possibilities)

3) $\angle 1 \cong \angle 2$ (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But $\angle 1$ is not congruent to $\angle 2$ (given)

5) So $\ell$ ∦ $p$ (only other possibility)

PLEASE HELP

Answer:

$11$ bushels of apples were sold

Step-by-step explanation:

Let

x----> bushels of peaches

y----> bushels of apples

we know that

$7x+6y=346$ -----> equation A

$x=y+29$ -----> equation B

substitute equation B in equation A and solve for y

$7(y+29)+6y=346$

$7y+203+6y=346$

$13y=346-203$

$13y=143$

$y=143/13=11$

PLEASE help with these questions??<br> there are 7 of them!<br> Thank you!!

We know in these kind of triangles that have a 90 degrees angle, we can do:

${a}^{2} + {b}^{2} = {c}^{2}$

so the first question:

$\sqrt{ {99}^{2} + {20}^{2} } = 101$

and then:

$b = \sqrt{ {17}^{2} - {15}^{2} } = 8$

so , when you want to rationalize , usually you must multiply the irrational factor as 1:

$\frac{ \sqrt{15} }{ \sqrt{15} } = 1$

so , now multiply:

$\frac{3}{ \sqrt{15} } \times \frac{ \sqrt{15} }{ \sqrt{15} } = \frac{3 \sqrt{15} }{15} = \frac{ \sqrt{15} }{5}$

in the next question,we know negative numbers in radical don't have any solution so 2 is correct,
