Solve for x and please show all work

Answer:

[tex]=132[/tex]

Step-by-step explanation:

[tex]A=2AB+(a+b+c)h[/tex]

[tex]AB=\sqrt{s(s-1)(s-b)(s-c)}[/tex]

[tex]s=\frac{a+b+c}{s}[/tex]

Now we have to solve for A:

[tex]A=ah+bh+ch+\frac{1}{2}\sqrt{-a^{4}+2(ab)^2+2(ac)-B^4(bc)^2-c^4[/tex]

[tex]4*10+3*10+5*10+\frac{1}{2}*\sqrt{-4^4+2*(4*3)^2*(4*5)^2-3^4+2*(3*5)^2-5^4}[/tex][tex]=132[/tex]

Answer: x = 25

Step-by-step explanation:

[tex]-\frac{4}{5} x + 7=-13[/tex]

1. First get X by itself by subtracting 7 from both sides

[tex]-\frac{4}{5} x=-20[/tex]

2. Multiply by the reciprocal of 4/5 on both sides

[tex](-\frac{5}{4} )-\frac{4}{5} x=-20(-\frac{5}{4} )[/tex]

3. Simplify

[tex]x=25[/tex]

Answer:

D. 8,9

Step-by-step explanation:

Square root of 74 is around 8.6 So we want to find numbers that are less than 8.6 and more than 8.6

angle bac and bca need to be acute and similar in size and angle abc needs to be an obtuse angle. This is the only triangle where angle abc is obtuse.

Answer:(-5,1) (-5,2) (-8,1)

Step-by-step explanation: first, the x reflects on the same distance away from the y-axis but the x points are negative, to make go from (5,1) to (-5,1) which puts on the y side.

Hope that helps!

Answer:

6

Step-by-step explanation:

It may be confusing to see why it would 6 instead of -6. The missing value in the X already includes the negative symbol. So if the 6 was the X value, then the negative sign would apply to the 6 making it - 6. The results would be:

⇒ [tex]-x = -6[/tex]

⇒ [tex]-6=-6[/tex]

Answer:

[tex]t = 10[/tex]

Step-by-step explanation:

Step 1:  Cross Multiply

[tex]\frac{5}{3} = \frac{t}{6}[/tex]

[tex](5 * 6) = (3 * t)[/tex]

[tex]30 = 3t[/tex]

Step 2:  Divide both sides by 3

[tex]\frac{30}{3} = \frac{3t}{3}[/tex]

[tex]10 = t[/tex]

Answer: [tex]t = 10[/tex]

Answer:

LCD=5 Final answer= 5/5 -> 5/1 -> to 5

Step-by-step explanation:

First, find the LCD(least common denominator) which is 5. This is done listing the multiples of each number in this case the lowest number is 5.

3/5 will stay the same but for 1/10 you need to convert it to the fraction 2/5 Next add the fractions together to get 3/5 + 2/5 = 5/5 of 5/1 or just 5

Answer:

LCD=5 Final answer= 5/5 -> 5/1 -> to 5

Answer: $0.35

Step-by-step explanation:

Answer: 7%

Step-by-step explanation:

Ok, we'll start by listing the facts.

Facts

Pack of pencils is $5

Total cost: 5.35

This means the sales tax is 35 cents, but we need to find the percentage to get the sales tax rate.

We can do this by dividing .35 by 5

0.35÷5= 0.07

Convert 0.07 to a percentage by multiplying it by 100

0.07x100= 7

Hence the sales tax rate is 7%. We can check to make sure this is correct by finding 7% of 5, and then adding the result to the 5.

7% of 5= 0.35

5+0.35= 5.35

Hope this helps, and brainliest would be appreciated :))

Answer:

T = 340 3 = 3 / T + 3 = 340

Step-by-step explanation:

"T" will be used as a variable, and to find out what "T" equals, we need to take the answer of the problem and take away "3", 343 - 3 = 340

"T" = "340"

T + 3 = 340
