What is the perimeter of this triangle ?
Answer:
36 units
Step-by-step explanation:
The two legs of this right triangle are 9 and 12. In order to find the length of the hypotenuse, you must plug in the 9 and 12 to the Pythagorean theorem:
a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse
If you plug in the values 9 and 12, you get:
9^2 + 12^2 = c^2
= 81 + 144 = c^2
= 225 = c^2
= 15 = c
This means that the hypotenuse is 15 units long. Now, you just need to add all the sides to get:
9 + 12 + 15
= 36 units
(Also as a fun fact, a Pythagorean Triple is when the three sides of a right triangle are integers. It is good to memorize a few of these, like 3-4-5, 5-12-13, 7-24-25 and 8-15-17. The largest side value is always the hypotenuse, and if you multiply all the sides by a scale factor, you can get other triples. If you knew the 3-4-5 triple, you might have noticed that 9 and 12 are 3 times each of the legs 3 and 4. From that information, you could just multiply the 5 by 3 to get 15 for the hypotenuse of this triangle, which might've made this problem a little easier)
Answer:
36
Step-by-step explanation:
Chen completed the division problem below. 0.9 StartLongDivisionSymbol 192.6 EndLongDivisionSymbol right arrow 9 StartLongDivisionSymbol 192.6 EndLongDivisionSymbol minus 18 = 12. 12 minus 9 = 36. 36 minus 36 = a remainder of 0 and a quotient of 21.4. What is Chen’s error? He included a 4 in the quotient, which does not belong. He multiplied the dividend by 100 instead of 10. He should have multiplied both numbers by 100. He did not subtract correctly in one of the steps.

WHY must the same operation be performed on both sides of an equation?
Answer:When you are given a problem, the two sides are equal, so they are equally weighted. As long as you do the same thing on both sides, they remain the same weight. The only way that one side can become "more weight" on a side is if you make a math mistake, and thus the answer would not satisfy the original equation

Answer:
1. y = 2m + 4
2. y = 3m + 1
3. y = 2/3m +1
4. y = 4m -6
Will answer any questions in the comments
Step-by-step explanation:
1. 1 -> 5 = 4
6 -> 14 = 8
8/4 = 2
y = 2m + 4
2. 2 -> -3 = -5
-5 -> 10 = 15
5/15 = 3
y = 3m + 1
3. 9 -> -3 = -12
11 -> 3 = -8
-8/-12 = 2/3
y = 2/3m + 1
4. 3 -> -2 = -5
6 -> -14 = -20
-20/-5 = 4
y = 4m - 6

x/2 - x = x/4 + 6
Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
[tex]\frac{x}2} -x=\frac{x}{4} +6[/tex]
Let's begin by getting rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators 2 & 4 (4).
[tex]4(\frac{x}2} -x)=4(\frac{x}{4} +6)[/tex]
Distribute:
[tex]\frac{4x}{2} -4x=\frac{4x}{4} +24[/tex]
Simplify:
[tex]2x-4x=x+24[/tex]
Combine like terms:
[tex]-2x=x+24[/tex]
Subtract [tex]x[/tex] from both sides of the equation:
[tex]-3x=24[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-3[/tex]:
[tex]x=-\frac{24}{3}[/tex]
Simplify:
[tex]x=-8[/tex]
(-5)²×(-5)⁴
answer it please
Answer:
15625
Step-by-step explanation:
(-5) ^ 2 * (-5) ^ 4
-5 to the second power is -25
-5 to the 4th power is -625
-25 * -625 = 15625
Just multiply 25 by 625 to get 15625 because negative * negative = positive

g. If you are going 70.0 mi/hr, how many miles do you travel in 0.681 hours!
Answer:
47.67 miles (in 40.86 minutes or 40 minutes and 51.6 seconds)
Step-by-step explanation:
Simple. Multiply these values together to cancel out the quantity in the denominator (cross multiply).
0.681 * 70 = 47.67
let x be the distance in miles:
70.0/1 = x/0.681
0.681 * 70 = 1 * x
47.67 = 1 * x
47.67 = x
32x – 14x = 288
with solution please and thank you
Answer:
x=16
Step-by-step explanation:
32x−14x=288
Step 1: Simplify both sides of the equation.
32x−14x=288
32x+−14x=288
(32x+−14x)=288(Combine Like Terms)
18x=288
18x=288
Step 2: Divide both sides by 18.
18x18=28818
x=16
Answer: x = 16
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
Step 1: Simplify 32[tex]x[/tex] − 14[tex]x[/tex] to 18[tex]x[/tex].
18[tex]x[/tex] = 288
Step 2: Divide both sides by 18.
[tex]x = \frac{288}{18}[/tex]
Step 3: Simplify [tex]\frac{288}{18}[/tex] to 16.
[tex]x[/tex] = 16

If the length of a rectangle in terms of x is x2 + 2x + 5, and its width is 2x + 3, what is the perimeter of this rectangle?
Answer:
6x
Step-by-step explanation:
Perimeter of rectangle is [tex]2x^{2} +8x+16[/tex].
What is perimeter of rectangle?The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.
Given
Length of a rectangle in terms of x = [tex]x^{2} +2x+5[/tex]
Width of a rectangle in terms of x = [tex]2x+3[/tex]
Perimeter of rectangle = 2(length + width)
P = [tex]2(x^{2} +2x+5 + 2x+3)[/tex]
P = [tex]2(x^{2} +4x+8)[/tex]
P = [tex]2(x^{2} )+2(4x)+2(8)[/tex]
P = [tex]2x^{2} +8x+16[/tex]
Hence, Perimeter of rectangle is [tex]2x^{2} +8x+16[/tex].

x=
2x-9x+17=-4
I have a answer but I’m not sure if I’m correct so I just want to double check.
Answer: x = 3
Step-by-step explanation: Simplify both sides
2x - 9x + 17 = -4
2x + - 9x + 17 = -4
Combine like terms
(2x + -9x) (17) = -4
-7x + 17 = -4
Subtract 17 from both sides
-7x + 17 - 17 = -4 - 17
-7x = -21
Divide both sides by -7
-7x/-7 = -21/-7
x = 3

x=3
