Find the value of x in the triangle shown below.

Choose 1 answer:

A- x=[tex]\sqrt{80}[/tex]

B- x=[tex]\sqrt{48}[/tex]

C- x=[tex]\sqrt{32}[/tex]

D- x=[tex]\sqrt{12}[/tex]

Answers

Answer:

Option A, x = [tex]\sqrt{80}[/tex]

Step-by-step explanation:

Pythagorean Theorem states: A² + B² = C² ( A and B are the legs, C is always the hypotenuse)

⇒ A² + B² = C²

⇒ 4² + 8² = x²

⇒ 16 + 64 = x²

⇒ 80 = x²

⇒ [tex]\sqrt{80} = \sqrt{x^{2} }[/tex]

⇒ [tex]\sqrt{80} = x[/tex]

She grocery shops 4 times a month. wat inequality can help to find the possible values of x the amount she can spend at the grocery store during each shopping trip. #2. if x =5 what inequality is true ( A. -2x>12 B. x - 2 < 7 C. 2x > 12 D. x - 7 > 2). #3. what is the value of x in this equation -4x = 42? hope anyone can help thx. Bye

Answers

Answer:

#1) 4x (less than or equal to) 320

#2) B (5 - 2 = 3 , 70

#3) -10.5

Hope this helps!

Step-by-step explanation:

1)

Ms. Sung is not able to spend more than 320 per month.

The best inequality for this would be

320 - 4x ≥ 0

Where x is the amount she spends per shopping trip

2)

x = 5 so let’s plug in 5 for x

Then in the 2nd column you put those bombers into the equation (so you would write 3(40)+2 3(50)+2 and 3(60)+2) and then in the third column you solve them (so 3(40)+2=122 3(50)+2=152 3(60)+2=182)

And then you graph them at (40,122) (50,152) and (60,182)

It's Number Line B. All symbols are supposed to be less than or equal to, just don't have that symbol on my keyboard.

Answer:

B

Step-by-step explanation:

2x-6 is [tex]\leq[/tex] 2 is what you start with and first, you would have to move the 6 to the other side to isolate the 2x. To do that, you do the opposite operation of the 6 which is addition. Add 6 to both sides to the eqaution would end up being 2x[tex]\leq[/tex]8. Now to isolate the x, we also have to do the opposite operation so divide the 2x and the 8 by 2. The eqaution would look like this x [tex]\leq[/tex]4. Number line B would show this ineqaulity as the arrow is going left to show that x is less than 4 but the dot is also shaded in which means that 4 can also be the answer as well. Hope this helps:)
