Answer: (x−3)(x+7)

Step-by-step explanation:

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x^2+7x−3x−21

=x^2+4x−21

Answer:

A. X^2+4x-21

Step-by-step explanation:

(x−3)(x+7)

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x2+7x−3x−21

=x2+4x−21

Answer:

C

Step-by-step explanation:

Since the figures are congruent then corresponding angles are congruent.

Then ∠ X = ∠ R , that is

∠ X = 135° → C

Answer:

AB = 74°

Step-by-step explanation:

Minor arc AB is equal to the measure of the central angle APB , then

∠ APB = 360° - 286° = 74° , thus

minor arc AB = 74°

Arc measure of minor arc AB on circle P =  74 degrees

In the given circle,

Arc measure of major arc = 286 degree

Since we know that,

Measure of complete circle = 360 degree

Therefore,

Angle of minor sector = 360 - 286

                                     = 74 degree

We also know that,

A circle sector is a segment or component of a circle made up of an arc and its two radii. A circle's sector can be compared to the form of a pizza slice. A sector is generated when two circle radii meet at both ends of an arc. An arc is merely a part of the circle's circumference.

Since,

Angle of sector = measure of arc

Hence,

Measure of minor arc = 74 degree.

Answer:

B; one solution

Step-by-step explanation:

Here, we want to get the number of solutions the system of linear equations has

From what we have in the diagram, we can see that the two lines cross at a point

The point at which these two lines meet is the solution to the system

What we are saying is that the (x,y) of the point at which the two equations meet represent the solution

Answer:

Option (1)

Step-by-step explanation:

Area of the composite figure ABCDEFGH = Area of rectangle ABGH - Area of rectangle CDEF

Area of rectangle ABGH = Length × Width

                                         = 14 × 7

                                         = 98 cm²

Area of rectangle CDEF = 9 × (7 - 4)

                                        = 27 cm²

Area of the composite figure = 98 - 27

                                                = 71 cm²

Option (1) is the correct option.

Answer:

ZK = 95 degrees

Step-by-step explanation:

Supplementary angles are when the sum of 2 angles equals 180 degrees. Since ZJ and ZK are supplementary, we can add both of them to equal 180 degrees.

ZJ + ZK = 180

Our first objective: find the value of x

(2x + 5) + (3x - 10) = 180

2x + 5 + 3x - 10 = 180

Combine like terms

5x - 5 = 180

Add 5 to both sides to isolate variable x

5x = 175

Divide both sides by 5 to isolate variable x

x = 35

Plug in x value for ZK expression

Here is the complete question

A tree is standing behind a building. 2/5th of the height of the tree can be seen and the rest is hidden by the building. The building is 12 metres high. What is the height of the tree?

If 2/5 of the tree can be seen the tree covers ( 1 - 2/5) 3/5 of the tree. If the  building is 12 metres high, it means that 2/5 of the building is 12m high

the height of the tree = 12 x (5/2) = 30m

Answer:

900<x<1100

Step-by-step explanation:

The third side must be greater than the difference of the other two sides

10000- 1000 < 10x

9000< 10x

Divide by 10

9000/10 < x

900 < x

The third side must be smaller than the sum of the other two sides

10000+1000 > 10x

11000>10x

Divide by 10

11000/10>10x/10

1100>x

900<x<1100

step 1 : see what variable you can take out , start with x see if there is x in the left and right side. and how many time you can take it out

next y same thing and then last z

with x = left side you x^2 and right side you have x = so u can take x out once left you with x

with y = left side y^4 and right side y^8 so you can take out y ^4 out left you with y^4

with z = left side z^3 and right side z ^5 you can take out z^3 left you with z^2
