The number that fills in the blank to make a perfect square trigeminal of the given expression is 81.

Given expression:

[tex]x^2+18x +[/tex] _

We have to find the number that will fill the blank.

A perfect square trigeminal is an algebraic expression that is of the form ax 2 + bx + c, which has three terms. It is obtained by the multiplication of a binomial with itself.

Let the number that fills the blank be a.

Hence, the expression becomes:-

[tex]x^2+18x +a[/tex]

To make it a perfect square geminal, the expression must be a perfect square of a binomial.

We know that,

[tex](x+y)^2=x^2+2xy+y^2[/tex]

Comparing it with given expression, we get

2xy = 18x and,

[tex]y^2=a[/tex]

Hence,

y = 9

a = [tex]9^2[/tex] = 81

Hence, the number that fills the blank is 81.

The maximum number of miles Julie can drive the car is 272 miles.

Let's check how:

Julie's budget for renting a car is $200.

number of days she'll rent a car is 3.

car rental per day is $44 + $0.25 per mile.

so to know maximum no. of miles she can drive

we'll first subtract the 3 days rent from Julie's budget = $200 - ( 3 x $44 )

= $200 - $132

= $132

Now, the left money is $68.

so, we will divide $68 by $0.25 to know how much miles she can drive.

= $68 ÷ $0.25

= 272 miles

Hence, the maximum number of miles Julie can drive the car for 3 days is 272 miles.

When two straight lines or rays intersect at a single endpoint, an angle exists formed. If 2 and 3 exists complements, and m2= 55°, then m3 = 90 - 55 = 35 degrees.

When two straight lines or rays intersect at a single endpoint, an angle exists formed.  The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Complements sum to 90 degrees.

If 1 and 2 are complements and m1 = 35°, then

m2 = 90 - 35 = 55 degrees.

Now if 2 and 3 are complements, and m2= 55°,

then m3 = 90 - 55 = 35 degrees.

The complete question is:

Given: 1 and 2 are complements, 2 and 3 are complements, and m1 = 35°. Prove: m3 = 35° Complete the missing parts of the paragraph proof. By then, we know that angle 1 is congruent to angle 3. The measure of angle 1 equals the measure of angle 3 by the definition of angles. Then, using the property, the measure of angle 3 is the degree.

Step-by-step explanation:

using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

given

[tex]log_{\frac{1}{7} }[/tex] 49 = n , then

49 = [tex](\frac{1}{7}) ^{n}[/tex]

49 = [tex](7^-1)^{n}[/tex] , that is

7² = [tex]7^{-n}[/tex]

since bases on both sides are equal then equate exponents

- n = 2 ( multiply both sides by - 1 )

n = - 2

27/4 , -3.2, -∛60 ,√48, 7.05 when arranged in ascending order we get:

Answer:

(1) p(x) = 7x³ + 4x² + 6 - 9x⁴

(2) p(x) = 1 + 3x - 9x⁵

(3) y = 9x² - x³ + x⁹

(4) f(x) = (x +3)(x-2)(x+5)

Step-by-step explanation:

Standard form has terms arranged from the highest to the lowest power

Degree is the highest power

Leading coefficient is the coefficient of the highest term

Leading term is the term containing the highest power

(x + 3) (x - 2)(x + 5)

(x + 3) (x - 2) = x² + x - 6 using the FOIL method
(x² + x - 6)(x +5) = x³ + 6x² -x - 30

Step-by-step explanation:

come on, we explained this already in previous questions. if you understood the explanations there, you should have been able to some that here without any problems.

again, standard form is the sorted polynomial from highest variable exponent to the lowest (as the potential constant at the end represents the x⁰ term).

the leading term is the first term on the left (with the highest exponent).

the leading coefficient is the factor in this leading term.

degree is the highest exponent used in the polynomial (again, given by the leading term).

so, what is still the problem ?

i have a slight problem with your handwriting. it is unclear, if there is 7x³ or 17x³. or 13x or 3x.

1.

p(x) = 17x³ + 4x² + 6 - 9x⁴

now, just sort this from the highest to the lowest exponent.

p(x) = -9x⁴ + 17x³ + 4x² + 6

if it should be 7x³ instead of 17x³, please use 7x³ in the polynomial.

degree = 4

leading coefficient = -9

leading term = -9x⁴

2.

p(x) = 1 + 13x - 9x⁵

again sort from highest to lowest exponent

p(x) = -9x⁵ + 13x + 1

again, if it should be 3x instead of 13x, please use 3x in the polynomial.

degree = 5

leading coefficient = -9

leading term = -9x⁵

3.

y = 9x² - x⁵ + x⁹

remember, y = f(x)

that is the same thing, means the same thing. it just gives the result variable a specific name.

again sort by exponent.

y = f(x) or p(x) or ... = x⁹ - x⁵ + 9x²

degree = 9

leading coefficient = 1

leading term = x⁹

4.

f(x) = (x+3)(x-2)(x+5)

this is really like the other question I just answered.

so, we always multiply 2 terms. that result we multiply by the third term. and if they're are more, then that result with the fourth term, and that with the 5th term,...

I usually start at the left :

(x+3)(x-2) = x² - 2x + 3x - 6 = x² + x - 6

now

(x² + x - 6)((x+5) = x³ + 5x² + x² + 5x - 6x - 30 =

= x³ + 6x² - x - 30

so,

f(x) = x³ + 6x² - x - 30

degree = 3

leading coefficient = 1

leading term = x³

The rectangular sign is 30 feet in length and 42 feet in width.

The perimeter of the rectangular sign = 144 ft

Let the width of the rectangular sign be x, and the length of the sign will be x-12

The formula for the perimeter of the rectangle:

P = 2(l+w)

where P = perimeter of the rectangle

l = length of the rectangle

w = width of the rectangle

Substituting the values in the formula we get:

144 = 2(x-12+x)

144 = 2(2x-12)
