Answer:
18Step-by-step explanation:
By similar triangles law:-
[tex]\frac{24}{2x} =\frac{30}{x+6}[/tex]
[tex]24(x+6)=30(2x)[/tex]
[tex]24x+24(6)=60x[/tex]
[tex]24x+144=60x[/tex]
[tex]\frac{36x}{36x} =\frac{144}{36}[/tex]
[tex]x=4[/tex]
Since AB=x+6+2x
[tex]AB=3x+6[/tex]
Substitute value of x
[tex]AB=3(4)+6[/tex]
[tex]AB=12+6[/tex]
[tex]AB=18[/tex]
Therefore, the third side of ΔABC is 18.

Which expression is equivalent to -6(-2/3+2x)?
plss hurry im timed
-4-12x
-4+2x
4-12x
4÷12x
Answers
Answer:
4 - 12x
Step-by-step explanation:
-6(-2/3 + 2x)
we can distribute by multiplying -6 by whats inside of the parenthesis ( -2/3 and 2x )
-6 * -2/3 = 4
-6 * 2x = -12x
4 - 12x would be the equivalent expression
Given expression to us is ,
→ -6( -2/3 +2x)
Simplify by multiplying each terms inside the brackets by -6 .
→ -6*-2/3 + 2x*(-6)
Simplify,
→ 4 -12x
Hence option 3 is correct .

Answers
Answer:
x = 20, angle B = 92 and angle c = 40
Step-by-step explanation:
3 angles in a triangle adds up to 180, and since A is 48, we have B + C = 132
6x - 28 + 2x = 132
=> 8x - 28 = 132
=> 8x = 160 and x = 20
B = 6 x 20 - 28 = 92
C = 2 x 20 = 40
Find point D on AB that is 3/4 of the distance from A to B
Answers
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.
a2+b2=c2 a 2 + b 2 = c 2 ,

If we want to multiply (x^3-3x^2+2x) with (x^3-2x^2+x), then we can set up a diagram shown below. The terms are along the outside. The stuff inside is the result of multiplying each pair of outer terms.
Example: x^3 times x^3 = x^6 in the top left cornerAnother example: 2x times x = 2x^2 in the bottom right corner.This is known as the box method to keep track of all the terms multiplied.
Once the table is filled out, we add up each term inside the boxes. Combine like terms if possible. Notice that I color-coded the like terms (eg: the x^3 terms are in green boxes).
The final answer is x^6 - 5x^5 + 9x^4 - 7x^3 + 2x^2

The sum of two one numbers, one of which is one thirds of the other, is 60. Find the smaller number
Answers
Answer:
x = 15
(y = 45)
Step-by-step explanation:
x + y = 60
x = y/3
y/3 + y = 60 /*3
y + 3y = 180
4y = 180 /÷4
y = 45
x = y/3 = 45/3 = 15
Answer:
15 smaller The other 45
Step-by-step explanation:
X= big
1/3(x) = small
x+1/3(x) = 60
Multiply both sides by 3 to eliminate the fraction
3x+x = 180
4x=180
x= 45 (big=45)
60-45= 15 (small = 15)
45/3=15
