Answer:

x = 2

Step-by-step explanation:

According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)

m<L = (7x + 9)° is an inscribed angle

m(KM) = 46° is its intercepted arc

Therefore:

7x + 9 = ½(46)

Multiply both sides by 2

2(7x + 9) = 46

14x + 18 = 46

14x + 18 - 18 = 46 - 18

14x = 28

14x/14 = 28/14

x = 2

Answer:

The answer is below

Step-by-step explanation:

PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm

The breadth of PQRS = a. Hence:

Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab

but Area of PQRS = 84 cm²

9a + ab = 84          (1)

In rectangle PXYS, length = QR = a cm, breadth = YS = b cm

Hence area of PXYS = length * breadth = (a)(b) = ab

But Area of PXYS = 21 cm²

ab = 21         (2)

substitute ab = 21 in equation 1:

9a + 21 = 84

9a = 84 - 21

9a = 63

a = 7 cm

ab = 21

7b = 21

b = 3 cm

Therefore a = 7cm, b = 3 cm

Answer: 3, 4, 6

Step-by-step explanation: equilateral triangle, square, regular hexagon

In a regular tessellation 3,4,6 sides can be tessellating regular

polygon.

A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.

First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.

A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.

A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Answer:

B

Step-by-step explanation:

First, we can determine the zeros of the function.

We can see that the graph passes through the x-axis at the points: x = -4, -2, and 1.

Therefore, we have three factors:

[tex](x-(-4)),\, (x-(-2))\text{ and } (x-(1))[/tex]

Thus, our function will be:

[tex]y=(x+4)(x+2)(x-1)[/tex]

Our answer is B.

Answer:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

              0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

Answer:

m = rise/run = 4/5.

Step-by-step explanation:

This line goes throught the "exact" grid intersections (-2, 0) and (3, 4).  As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise').  Thus, the slope of this line is m = rise/run = 4/5.
