One may note you're kinda missing the factors provided, but anyhow, it factors to

$\bf 3a^2+6a-2a-4\implies (3a^2+6a)-(2a+4)
\\\\\\
3a(a+2)~~-~~2(a+2)\implies \stackrel{common~factor}{(a+2)}[3a-2]$

The legs of a right triangle are 3 units and 8 units. What is the length of the hypotenuse? Round your answer to the nearest hun

Alisiya [41]

Answer:

<h2>8.54 units</h2>

Step-by-step explanation:

Given,

Perpendicular ( p ) = 8 units

Base ( b ) = 3 units

Hypotenuse ( h ) = ?

Using Pythagoras theorem:

${h}^{2} = {p}^{2} + {b}^{2}$

plug the values

${h}^{2} = {8}^{2} + {3}^{2}$

Evaluate the power

${h}^{2} = 64 + 9$

Calculate the sum

${h}^{2} = 73$

Squaring on both sides

$h = \sqrt{73}$

Calculate

$h = 8.54$ units

Hope this helps..

Best regards!

Write an inequality for this situation

Rainbow [258]

Answer: $E \ge 31$

Reason:

"at least 31 points" means "31 or more".

So either E = 31 or E > 31 (meaning Embiid scored 31 points or he scored more than 31 points).

Choice A looks like the closest match assuming the inequality sign is $\ge$

Saying E > 31 instead of $E \ge 31$ would be false because it leaves out the case E = 31.

Chloe notices that segment ST and segment VW are congruent in the image below.

IgorLugansk [536]

The SAS similarlity theorem is the type of similarlity that show that two triandles are similar by showing that two of the sides are similar with the angle between the two sides also similar.

Thus, given that <span>segment ST and segment VW are congruent, and also from the image it can be seen that angle S is congruent to angle V.

Thus, to show that </span>ΔSTU ≅ ΔVWX, we have to show that <span>US≅XV.

There</span>fore, the <span>step that could help her determine if ΔSTU ≅ ΔVWX by SAS is<span> US≅XV</span></span>

svp [43]

The two numbers that adds up to 23 and mutliplies to 26 are 1.19 and 21.808.

21.808 + 1.19 ≈ 23
21.808 × 1.19 ≈ 26
