The perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and W is the width of the rectangle. Can the perimeter of the rectangle be 64 units when its width is 11 units and its length is 20 units?

a. No. If the length is 20 and the width is 11, the perimeter is P = 20 + 22 = 42, not 64.
b.No. If the length is 20 and the width is 11, the perimeter is P = 40 + 22 = 62, not 64.
c. Yes. If the perimeter is 64 units and the width is 11 units, then P + W is greater than 40.
d. Yes. If the perimeter is 64 units and the width is 11 units, then P + W is less than 40.

C-1

Answer:

A = 2, B = 3. C = 1

Step-by-step explanation:

A, B, and C correspond to the coefficients of the terms. (ax² + bx + c)

Therefore:

A = 2

B = 3

C = 1

Answer:

x = ± 10

Step-by-step explanation:

Given

y = x² - 100 ← a difference of squares , that is

y = x² - 10² = (x - 10)(x + 10)

To find the x- intercepts let y = 0 , that is

(x - 10)(x + 10) = 0

Equate each factor to zero and solve for x

x - 10 = 0 ⇒ x = 10

x + 10 = 0 ⇒ x = - 10

Answer:

Step-by-step explanation:

The domain indicates all the x values which are {2, 6, 9} in order from least to greatest. As long as none of these numbers is the same, then our relation is also a function. Choice A. is the one you want.

Answer:

Step-by-step explanation:

[tex]28y^{7} *x^{4} *u^{3} \\8x^{4} *u^{5}[/tex]

rewrite those 2 terms to better see what they have in common

[tex]4*7 *x^{4} *u^{3} *y^{7} \\4*2*x^{4}*u^{3} *u^{2}[/tex]

because, 4*7 =28, 4*2=8, u³*u² =u^5, and multiplication is commutative

The greatest common factor is:

[tex]4x^{4} u^{3}[/tex]

Answer:

√13 + 3 = x

-√13 + 3 = x

Step-by-step explanation:

y = x² - 6x - 4

0 = x² - 6x - 4

0 + 13 = x² - 6x - 4 + 13

13 = x² - 6x + 9

13 = (x-3)²

±√13 = x-3

±√13 + 3 = x

√13 + 3 = x

-√13 + 3 = x

Answer:

Suppose x∈R is such that x+20x=p is a prime. Then x2−px+20=0 , and this equation has a solution x∈R if and only if p2–80≥0 . So the primes which admit no real solution are those that satisfy p<80−−√ , or 2 , 3 , 5 , and 7 . ■

Step-by-step explanation:

E? <3

The primes which accept no real solution exist as those that satisfy

p<[tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.

A prime number exists as a real number greater than 1 whose only factors that exist are 1 and itself. A factor exists as an entire number that can be divided evenly into another number. The first prime numbers exist 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Numbers that contain better than two factors exist named composite numbers.

If the function f(x) = (20/x) + x = k. Suppose x∈R exists such that x+20x=p exists a prime. Then [tex]$x^2-px+20=0[/tex], and this equation contains a solution x∈R if and only if [tex]$p^2-80[/tex] ≥ 0. So the primes which accept no real solution exist as those that satisfy p < [tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.

Explanation:

The vertex of f(x) is (-3,4)

The vertex of -f(x) is (-3,-4). Note the y coordinate flips in sign. This is effectively because y = f(x).

Shifting the vertex down 2 units will get us to g(x) = -f(x)-2

So that's how we end up with (-3, -6)

Answer:

The correct answer is – 1/2

Answer:

The answer is -1/2

Step-by-step explanation:

If we compare this with y = mx + c, we can do a comparison. m is the slope and c is the added constant.

Since y = -1/2 x + 1/4,

m = -1/2

Since m is the slope, the slope is -1/2.

9x - 2y = 19, 7x = 21

7x = 21

=> x = 21/7

= x = 3 —————(1)

9x - 2y = 19

=> 9(3) - 2y = 19 [From (1)]

=> 27 - 2y = 19

=> -2y = 19 - 27

=> -2y = -8

=> y = -8/-2

=> y = 8/2

=> y = 4

So, x = 3 and y = 4.

Answer:

32 square units.

Step-by-step explanation:

The shape is made up of three parts, a rectangle in the middle, and two identical triangle on each side.

Rectangle:  base = 2, height 8, area = 16

Each triangle: (vertical) base = 8, (horizontal) height = 2

Area = base * height /2 = 2*8/2 = 8

Total area = 8 + 16 + 8 = 32

Answer:

law of cosines states c^2=a^2+b^2-2abc

b^2=26^2+24^2-2(26×24)cos 134°

b^2=676+576-1248cos134°

cos134= -0.6946

b^2=1252-12(-0.6946)

12×(-0.6946)= -8.3352

b^2=1252-(-8.3352)

b^2=1252+8.3352

b^2=1260.33

b=√1260.33

b=35.50
