√5(√10 + √3) = √(5 · 10) + √(5 · 3) =

= √50 + √15 = √(25 · 2) + √15 =

= √(5² · 2) + √15 = 5√2 + √15 ← the end

HELP ASAP!! GIVING 20 POINTS AND BRAINLIEST!!! Solve for x. y=7x-7z-9

svetlana [45]

We just need to see everything that is not x as a number.

if I asked
$5 = 7x - 7(2) - 9$
we would solve it by combining like terms first. but, if I tell you not to do that, we would add 9 and 7(2) to both side and end up with
$5 + 7(2) + 9 = 7x$
we would then divide both sides by 7
$\frac{5 + 7(2) + 9}{7} = x$

math is always math... it's just how we look at it. so, do the same steps!
$y = 7x - 7z - 9$
add 9 and 7z to both side
$y + 7z + 9 = 7x$
divide both sides by 7
$\frac{y + 7z + 9}{7} = x$

Which angles are supplementary to 1 ( Select all that apply)?

bagirrra123 [75]

<h3>2 Answers: Angle 4 and angle 2</h3>

==================================================

Explanation:

Supplementary angles add to 180 degrees. Visually, supplementary angles can be glued together to form a straight angle or a straight line.

We see that happens with angles 1 and 4, and this also happens with angles 1 and 2. This is why these two angles make up the answer.

--------------

The other answer choices can be ruled out.

Angles 1 and 9 would be congruent if we knew the shallow sloping lines were parallel. The only time angles 1 and 9 are supplementary is if both are 90 degrees. In any other case, they are not supplementary angles.

Angles 1 and 12 are same side exterior angles. They would be supplementary if the shallow sloping lines were parallel. However, if you extend out each line, you'll see that they eventually intersect. Parallel lines never intersect.

Question 1 of 10

Radda [10]

Answer:

C is correct

Step-by-step explanation:

${x}^{2} = 18 \\ x = \frac{ + }{} \sqrt{18} = \frac{ + }{} \sqrt{9 \times 2} = \\ x = \frac{ + }{} \sqrt{9} \times \sqrt{2} \\ x = \frac{ + }{} 3 \sqrt{2}$
