which expression is equivalent to 4x^2 sqrt 5x^4 • 3 sqrt 5x^8 if x ≠ 0
Answer:
B
Step-by-step explanation:
The equivalent expression is [tex]16x^{8}[/tex]. So, the correct option is B.
Given:
The given expression is:
[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0[/tex]
To find:
The equivalent expression.
Explanation:
We have,
[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8}[/tex]
On simplification, we get
[tex]=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})[/tex]
[tex]=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})[/tex]
[tex]=12(x^{8})(5)[/tex]
[tex]=16x^{8}[/tex]
Therefore, the correct option is B.

Step-by-step explanation:
Step 1: Define
-3x + 40 = -23
Step 2: Solve for x
Isolate x term: -3x = -63Isolate x: x = 21Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -3(21) + 40 = -23Multiply: -63 + 40 = -23Add: -23 = -23Here we see that -23 does indeed equal -23.
∴ x = 21 is the solution to the equation.

8
Answer:
8
Step-by-step explanation:
it's multiplied by 2 as you go to triangle 2
Answer:
x = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{5}{10}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
5x = 40 ( divide both sides by 5 )
x = 8
In order for Josh to graph the solution to the inequality 4x - 2y > 6, which of the following steps does he need to use? Select all that apply.
Shade above the line.
Solve the inequality as y < 2x-3.
Draw the line y=2x-3 as a solid line.
Draw the line y=2x-3 as a dashed line.
Shade below the line.
Solve the inequality as y> 2x-3.
Solve the inequality as y < 2x-3.
Draw the line y=2x-3 as a dashed line.
Shade below the line.
Josh needs to follow the steps to draw the required inequality graph.
Solve the inequality y < 2x - 3 by solving for the x and y-interceptDraw the straight line y < 2x - 3 as a dashed line (since we have less than sign )Shade below the line. (Below the line are shaded for inequality sign that is "less than")Inequality expressions are expressions that are not separated by an equal sign.
Given the inequality expression 4x - 2y > 6,
Dividing through by 2 will give:
4x/2 - 2y/2 > 6/2
2x - y > 3
Make y the subject of the formula
-y > -2x + 3

A school lunch costs $2.50. A monthly lunch pass costs $40.00. Which inequality represents the number x of lunches you must purchase for the monthly pass to be a better deal?
Answer:
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Step-by-step explanation:
Given that:
Cost of each lunch = $2.50
Cost of monthly lunch pass = $40.00
Number of lunches = x
For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore
Cost of lunch * Number of lunches > Cost of monthly lunch pass
2.50x > 40.00
Hence,
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Answer:
2.50x > 40.00
$2.50 times a number of lunches is greater than $40.

Find the missing length of the triangle.
a=in
Answer:
a=9
Step-by-step explanation:
a^2+b^2=c^2
a^2+5.6^2=10.6^2
a^2+ 31.36=112.36
-31.36 -31.36
a^2=81
a=[tex]\sqrt{81}[/tex]
a=9
Answer:
9in
Step-by-step explanation:
is a right triangle so you can use Pythagorean Th.
(10.6)²= (5.6)² + a², subtract (5.6)² from both sides
(10.6)²- (5.6)² = a²
81 =a², squareroot both sides
√81= √a²
±9 = a we only consider the positive solution because we use it for measurements so a=9

Answer:
f(-3) = -16
Step-by-step explanation:
Given piecewise function is,
f(x) = 5x - 1 If x < -2
x + 3 If x ≥ -2
We have to find the value of he function when x = -3
Since x = -3 is less than x = -2,
Piece of the function to be considered,
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -16

Answer:
7/13
Step-by-step explanation:
Let's call x= numerator
We know that :
Denominator= x+6
And
(numerator +2)/(denominator +2) = 3/5
So
(x+2)/(x+6+2)=3/5
(x+2)/(x+8)=3/5
(x+2)*5=(x+8)*3
5x+10=3x+24
2x=14
x=7
In the end
Numerator= x =7
Denominator=x+6 = 13
So the original number is 7/13

SOLVE AND SHOW WORK PLSSSS!! Find the length of the missing sides. Do not round (leave in simplified radical form).
Answer:
For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13
Step-by-step explanation:
For the first triangle,
cos(45°)=7/hypotenuse
hypotenuse×cos45=7
hypotenuse×√2/2=7
hypotenuse=14/√2=7√2
We can now find the adjacent side using Pythagorean theorem,
√(7√2)²-7²=7
For the second triangle,
cos(30°)=adjacent/hypotenuse
but cos 30=√3/2
√3/2=adjacent/26(cross multiply and simplify)
26√3/2=13√3
To find the opposite length,
√(26)²-(13√3)²=13
