Answer:

<h2>\huge \: b) \: 59 \: i {n}^{2}</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about</h3>
  • area of triangles
  • area of rectangle
  • PEMDAS
<h3>tips and formulas:</h3>
  • rectangle opposite sides are equal
  • area of rectangle:l×w
  • area of triangle:½×h×b
<h3>let's solve:</h3>

the area of the rectangle is

4×7 in²

28 in²

the area of above triangle is

½×6×7 in²

3×7 in²

21 in²

the area of left side triangle is

½×5×4 in²

2×5 in²

10 in²

therefore,

the area of the polygon is

28+21+10 in²

<h3>59 in²</h3>

Mademuasel [1]

Answer:

1. D. Teorema.

2. A. Axioma.

Step-by-step explanation:

En matemáticas, un conjunto de proposiciones que deben estar respaldadas por una prueba adecuada basada en el razonamiento se denomina teorema. Se puede demostrar plenamente que todos los teoremas matemáticos son verdaderos mediante el razonamiento.

Sin embargo, un axión es evidente por sí mismo y no necesita ser probado. Es un hecho ya establecido.

PLS HELP! 7x +10y= -23<br><br> 7x + 6y = - 39
mote1985 [20]
4y = -23 + 39
4y = 16
y = 4

Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9

x = -9
y = 4

What’s the least common denominator for 1/6 and 7/8?
Alexandra [31]

Answer:

24

Step-by-step explanation:

Here's how we construct the LCD:

Factor the denominators 6 and 8:  6 = 2*3 and 8 = 2*2*2

The LCD involves 2*2*2 as well as 3:

LCD:  2*2*2*3 = 24.  Note that 24 is divisible by both 6 and 8.  There is no smaller LCD that is divisible by 6 and 8 both.

I need help on this question anyone know this ?
WITCHER [35]

Answer:

y = 4(2)^{x}

Step-by-step explanation:

An exponential function in standard form is

y = a b^{x}

Use ordered pairs from the table to find a and b

Using (0, 4), then

4 = a b^{0} ( note that b^{0} = 1 ), so

a = 4, then

y = 4 b^{x}

Using (1, 8)

8 = 4 b^{1} = 4b ( divide both sides by 4 )

b = 2

y = 4 (2)^{x} ← represents the values in the table
