Answer:

$\boxed{ \rm(6x)²-(5)²}$

Step-by-step explanation:

Given expression/polynomial :

$3 6{x}^{2} - 25$

Let's evaluate.

We can re-write the polynomial as

$6 {}^{2} x {}^{2} - 5 {}^{2}$

Further

${(6x) {}^{2} - 5 {}^{2} }$

Hence, the expression is equivalent to last Choice, (6x)²-(5)².

Marissa notices that the top of the net is 20 inches higher than the tallest player on the team. The net is less than 90 inches

Vika [28.1K]

No, the inequality uses less than or equal to, but it should be less than. The relationship could be written as h + 20 < 90. This says that the tallest player’s height plus 20 inches is less than 90 inches.

In the figure, ∆ABC~∆XYZ. What is the perimeter of ∆ABC? Show your work.

Elina [12.6K]

Answer:

49 units

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BC}{YZ}$ = $\frac{AB}{XY}$ , substitute values

$\frac{BC}{44}$ = $\frac{11}{22}$ ( cross- multiply )

22BC = 484 ( divide both sides by 22 )

BC = 22

------------------------------------------------

Similarly

$\frac{AC}{XZ}$ = $\frac{AB}{XY}$ , substitute values

$\frac{AC}{32}$ = $\frac{11}{22}$ ( cross- multiply )

22AC = 352 ( divide both sides by 22 )

AC = 16

Thus perimeter of Δ ABC is

perimeter = AB + BC + AC = 11 + 22 + 16 = 49 units

Answer:

g(x) = |x-7|+4

Step-by-step explanation:

If we imagine trying to find the vertex of f(x) or the lowest part, we can always input x and y into each equation and see if they equal on either side.

The vertex is at points (7,4)

4=|7-7|+4 : 4=4.

^Answer needed ASAP! Solve x2-6x=-5 by completing the square. show ALL work

Have a nice day, be safe and healthy :)

Hope this helped

formula:

(a+b)^2

= a^2+2ab+b^2

Here, we have x^2 (as in a^2)

and -6x (as in 2ab), which, we're missing the b^2

(I'm not really sure how to describe this but bare with me)

-6/2 (-6 is from the -6x) = -3 (the b)

-3^2 = -3*-3 which is equal to 9 (positive 9)

Writing it out -

x^2-6x+9 = -5

- Addition of inequality -

Since we add 9 to the left side, we have to add 9 to the right side; which gives us:

x^2-6x+9=4

Next, lets put the x^2-6x+9 as in (a+b)^2:

(x-3)^2 = 4

Then let's do the square root of equality (square rooting both sides) :

x-3 = 2

Finally lets add 3 to both sides

x = 5

THE ANSWER IS x=5

Have a nice day, be safe + healthy - Hope this helped
