Answer:
(b) commutative property
Step-by-step explanation:
The "simplified" expression has the positions of the last two terms in the sum swapped. The property of addition that lets you change the order of the terms is the commutative property of addition.
If x > 0, what is the difference of
[tex]6x \sqrt{14x} - 5 \sqrt{56 {x}^{3} } [/tex]in simplest radical form?
Answer:
[tex]\longmapsto \sf \: \: - 14x \cdot\sqrt{14x}[/tex]
Step-by-step explanation:
[tex] \sf \: if \: x > 0 [/tex]
[tex] \sf 6x \sqrt{14x} - 5 \sqrt{56 {x}^{3} } [/tex]
[tex] \sf Let's \: solve \: for \sqrt{56 {x}^{3} } \: first, \\\longmapsto \sf \sqrt{56 {x}^{3} } = \sqrt{14 \times 4 {x}^{2} \times x } \\ \sf \longmapsto \sqrt{56 {x}^{3} } = 4x \sqrt{14x} [/tex]
Substituting above value in given equation,
[tex]\longmapsto \sf 6x \sqrt{14x} - 5 \sqrt{56 {x}^{3} } \\ \longmapsto\sf 6x \sqrt{14x} - 5 \times 4x \sqrt{14x} \\ \longmapsto \sf \: 6x \sqrt{14x} - 20x \sqrt{14x} \\\longmapsto \sf \: \sqrt{14x}(6x - 20x) \\ \longmapsto \sf \: \: - 14x \cdot\sqrt{14x}[/tex]

what is the distance formula?
Answer:
Distance formula. The formula for distance, if you know time (duration) and the average speed, is: d = v x t. where v is the velocity (average speed), t is the time and d is distance, so you can read it as Distance = Speed x Time. The result will depend on the unit of the speed metric, for example if speed is given in mph,
Step-by-step explanation:
A (m 1 ,n 1) and B (m 2 ,n 2) are the coordinates of the two given points in the coordinate plane.
The distance between the two points can be calculated using the distance formula, d = √ (m2 - m1)2 + (n2 - n1)2
Finally, express the given solution in proper units.

what is the area of the figure
Step-by-step explanation:
make the figure into 1 rectangle with dimensions 25 and w,and rite triangle with hypotenuse = 18 and h = 8
applying Pythagoras theorem
18^2 = 8^2 + b^2
b^2 = 260
b = 2√65ft
area of rectangle = 2√65 * 25= 50√65
area of triangle = 1/2 * 2√65*8 = 8√65
total area = 58√65 ft^2

Which is the completely factored form of 4x2 28x 49? (x 7)(4x 7) 4(x 7)(x 7) (2x 7)(2x 7) 2(x 7)(x 7)
The completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)
How to find the factors of a quadratic expression?If the given quadratic expression is of the form ax^2 + bx + c, then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:
[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]
Then writing b in terms of alpha and beta would help us getting common factors out.
Sometimes, it is not possible to find factors easily, so using the quadratic equation formula can help out without any trial and error.
For this case, the given quadratic expression is:
[tex]4x^2 + 28x + 49[/tex]
So we've to find two numbers such that:
Their sum = b = 28
Their product = [tex]ac = 4\times 49 = 196[/tex]
We can see that 196 is square of 14, and that 14 added twice forms 28, thus:
14 + 14 = 28
14×14 = 196
Writing b = 28 as sum of 14 twice, we get:
[tex]4x^2 + 28x + 49 = 4x^2 + 14x + 14x +49 \\4x^2 + 28x + 49 = 2x(2x+7) + 7(2x + 7)\\4x^2 + 28x + 49 = (2x+7)(2x+7)[/tex]
Thus, the completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)

help! which expression is equivalent to 14x + 35 - 21 y
Answer:
7(2x + 5 - 3y)
Step-by-step explanation:
Looking at the Factors below the question, what do you notice?
I notice that 14, 35 and 21 all have a GCF of 7
With this, we can now start factoring, but before we start, keep in mind that we need to find terms that when multiplied with 7 give us 14x, 35, and -21y.
Be careful with the signs ( + and -) when factoring!14x + 35 - 21y
7(2x + 5 - 3y)
Check you answer to make sure if results in our original expression:
7(2x + 5 - 3y) <== distribute seven
7(2x) + 7(5) + 7(-3y)
14x + 35 - 21y
Therefore, we have correctly factored the expression, and the correct answer is 7(2x + 5 - 3y)
Hope this helps!
13. If ZA and ZB are supplementary angles and ZA
is three times as large as ZB, find the measures
of ZA and ZB.
Answer:
A. ZA+ZB =180
B. ZA is 135 and ZB is 45
Step-by-step explanation:
Step-by-step explanation:since ZA and ZB are supplementary
ZA+Zb =180°
But ZA=3ZB
∴ 3ZB+ZB=180° ⇒4ZB=180°
∴ZB =45
