Answer:

Step-by-step explanation:

945=2x+2x+x+x+x

945=7x

135=x

smaller demension: 135

larger: 2*135=270

Area=135*270=36,450

Answer:

Step-by-step explanation:

The total length of the fencing that he purchased is 945 feet.

The total length covered by the fencing material is

2x + 2x + x + x + x = 945

9x = 945

Dividing the left hand side and the right hand side of the equation by 9, it becomes

9x/9 = 945/9

x = 105 feet

The smaller value is 105 feet

The larger value is 2x = 105 × 2 = 210 feet.

The formula for determining the total area of the rectangular enclosure is expressed as

Area = length × width

Area = 210 × 105 = 22050 ft²

<h3>You have the correct answer. It is choice B. Nice work.</h3>

K is the midpoint, so $\overline{IK} \cong \overline{GK}$ and $\overline{JK} \cong \overline{HK}$ , and along with the congruent vertical angles ( $\angle GKH \cong \angle IKJ$ and $\angle GKJ \cong \angle IKH$ ), you would use the SAS (side angle side) congruence theorem to prove the inner pairs of triangles to be congruent.

So, $\triangle HKG \cong \triangle JKI$ (top and bottom triangles) and $\triangle GKJ \cong \triangle IKH$ (left and right triangles).

Then through CPCTC, we can show the corresponding pieces are congruent leading to $\overline{GH} \cong \overline{JI}$ and $\overline{GJ} \cong \overline{HI}$ showing the opposite sides of the quadrilateral are congruent. Therefore we do have a parallelogram and enough information to prove it as such.

Side note: CPCTC stands for "corresponding parts of congruent triangles are congruent".

Find the value of c so that (x+1) is a factor of the polymonial p(x)=5x^4+7x^3-2x^2-3x+c

Andru [333]

Answer:

BRAINLIEST PLZZZZ

Step-by-step explanation:

Also given that (x+1) is factor of given polynomial p(x).

Need to determine value of constant c.

We will be solving above problem using factor theorem.

Factor theorem says that if ( x – a) is a factor of any polynomial f(x) , then f(a) = 0.

As in our case f(x) = p(x) and factor of p(x) is (x + 1) , which can be rewritten as (x – ( -1)) , so "a" in our case is -1 .

According to factor theorem p(-1) = 0

On substituting x = -1 , in given expression of p(x) we get

Hence value of c in the given polynomial is 1

Your making a mosaic design on a square table top. You have already covered half of the table top with 150 1-inch square tile pi

Luden [163]

Since this table top is a square, we would expect it to have the same sides. So if your halfway, we can add another 150 1-inch square tile pieces, which makes it 300 inches (150 + 150 = 300; then multiplied by 1 inch).

(a) The dimension can be described using length and width values. So, its dimension is 300 x 300 inches.

(b) The diagonal from one corner to the opposite corner is calculated using the formula: d= √2a, where a represents the measurement of 1 side. Using the values and formula, the diagonal therefore measures 424.26 inches.

The back of jake's property is a creek. Jake would like to enclose a rectangular area, using the creek as one side and fencing f

kow [346]

Answer:

The maximum possible area of the pasture is 26,450 feet square.

Step-by-step explanation:

Let us assume the width of the rectangular area = m ft

and the length of the area = k ft

Also assume: ( one side with k units IS NOT FENCED)

So, the total perimeter of the fencing is:

2 m + k = 460

or, k = 460 - 2m ........ (1)

Now, AREA OF THE RECTANGULAR PORTION = Length x Width = k x m

Put k = 460 - 2m

We get: A = m (460 - 2m)

or, A = 460 m - 2m²

We need to find the maximum for the parabolic function A = 460 m - 2m²

The function has a maximum value as the quotient in front of x^2 is negative: -2 < 0

A (max) = $c-\frac{b^2}{4a}$ where a = -2, b = 460, c = 0

= $-\frac{(460)^2}{4(-2)} = 26,450$

A max = 26,450 sq ft.

The maximum possible area of the pasture is 26,450 feet square.
