Step-by-step explanation:
Let 1st side of triangle be x
so,
length of given side will be x, 2x, 6+x
we know that,
perimeter of triangle = 34
x+2x+(6+x)= 34
4x+6= 34
4x = 34-6
x= 28÷4
:x= 7
2x = 7*2= 14 ft
6+x = 6+7 = 13 ft

Find the value of k for which the line y = kx + 6 is a tangent to the curve x^2 + y^2 – 10x + 8y = 84
Answer:
k = 1/2
Step-by-step explanation:
input y = kx +6 into the equation of the curve x² + y² – 10x + 8y = 84
x² + (kx + 6)² - 10x + 8(kx + 6) = 84
expand:
x² + k²x² + 12kx + 36 - 10x + 8kx + 48 = 84
simplify by collecting like terms:
x² + k²x² + 20kx - 10x + 84 = 84
subtract 84 on both sides to bring it to the left:
x² + k²x² + 20kx - 10x + 84 - 84 = 0
x² + k²x² + 20kx - 10x = 0
factorise out x:
x²(1 + k²) + x(20k - 10) = 0
using the discriminant b² - 4ac where b is 20k - 10, a is 1 + k² and c is 0, substitute them in the formula b² - 4ac:
b² - 4ac
(20k - 10)² - 4(1 + k²)(0) = 0
the part highlighted in bold is gone because it's all multiplied by 0, so we are left with (20k - 10)² = 0
(20k - 10)² is the same as
(20k - 10)(20k - 10)
equate both to 0
20k - 10 = 0 and 20k - 10 = 0
add 10 on both sides
20k = 10 and 20k = 10
divide 20 on both sides
k = 10/20 and k = 10/20 which are both the same
10/20 is simplified to 1/2
k = 1/2

A stack of books is 24 inches high.
Each book in the stack is 3/4 inch thick
How many books are in the stack?
Answer:
32
Step-by-step explanation:
Let's say n such books make up the stack.
If each book is 3/4 inch thick, it contributes 3/4 to the total height of the stack – 24 inches.
==> number of books × 3/4 = 24
(to get this result add the heights of n such book, and equate it to 24. You'll get something like:
3/4 + 3/4 +. . . . n times = 24
And that's what's meant by 3/4 × n = 24)
==> n × 3/4 = 24
multiply both sides by 4
==> n × 3 = 24 × 4
divide both sides by 3
==> n = (24 × 4)/3
==> n = 8 × 4
==> n = 32
We assumed the number of books to be n.
so the answer is:
32 books, each if height 3/4 inch, are required to build a stack 24 inches high.

Answer:
Step-by-step explanation:
Evaluate the expression for x = -4, y=-2, and z=-3.
x(y+z)^2?
Answer:
- 100
Step-by-step explanation:
x (y + z)²
= (-4) [(- 2) + (- 3)]²
= - 4 * (-5)²
= - 4 × 25
= - 100
Hope it helps ⚜
Step-by-step explanation:
we take the values given and we substitute in the equation above.
value of x=-4
y=-2
z=-3
hence we can solve for the equation above
-2(-2+-3)^2
we for everything in brackets first
(-2+-3)=-5
(-5)^2=25hence after solving we multiply by -2
-2(25)=-50
indeed that is my solution.
Solve for x
-1/5x-2/5=4/3x+1
Answer:
x = -21/23 or 0.913 (rounded to the nearest thousandth)
Step-by-step explanation:
Step 1: Add 2/5 to both sides
1. -1/5x - 2/5 + 2/5 = 4/3x + 1 + 2/5
2. -1/5x = 7/5 + 4/3x
Step 2: Subtract 4/3x from both sides
1. -1/5x - 4/3x = 7/5 + 4/3x - 4/4x
2. -23/15x = 7/5
Step 3: Multiply both sides by 15
1. (15)-23/15x = 7/5(15)
2. -23x = 21
Step 4: Divide both sides by -23
1. -23x/-23 = 21/-23
2. x = -21/23 or 0.913 (rounded to the nearest thousandth)

b) Find the value of w.
Give each answer as an integer or as a fraction in its simplest form.
The scale factor from shape A to shape B is 0.75 with w = 5.25 cm.
What is scale factor?The size by which the shape is enlarged or reduced is called as its scale factor.
Scale factor from shape A to shape B = [tex]\frac{3}{4}[/tex] = 0.75
It can be calculated by dividing the length of one side of the polygon to the corresponding side of the similar polygon. Keep the length of the side of the original figure in denominator and length of the side of the transformed figure in the numerator.
