What is the sum of the degree measures of the complement and the supplement of a 16° angle?​

Answer:

Answer A

as taught to us till now

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

I hope this helps :) I got it CORRECT also i added the Steps if your teacher asked for steps :)

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

Step-by-step explanation:

Unit Conversion:

a≈5.03m

h≈2.97m

Solution

V=a2h 3=5.032·2.97 3≈25.0551m³

Answer:

(2x+9)^2

Step-by-step explanation:

Factor the equation by using the perfect square rule: a^2+2ab+b^2=(a+b)^2 or a^2-2ab+b^2=(a-b)^2 depending on the trinomial

Answer:

River C: 2875, River D: 2675

Step-by-step explanation:

Subtract 200 from 5550. Then divide your  difference (5350) by 2 to get 2675. Add 200 to one of your 2675s to get river C's length.

Answer: $906.51

Step-by-step explanation:

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

did they give u some initial numbers to substitute with or something?

Answer:

xy^4 z^3 ( 16x + 33y^4 z^2)

Step-by-step explanation:

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

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

3(35) - 10

Use PEMDAS

105 - 10

95

Answer:

2(x-1)^2-15

Step-by-step explanation:

2x^2-4x=2(x-1)^2-2

insert that in:

f(x)=2(x-1)^2-2-13=2(x-1)^2-15

a=2,h=-1,k=-15

Answer:

-3 & -12

Step-by-step explanation:

-3 * -5 =36

negative multiplied by a negative it will give you a positive

-3+(-5)=-15

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.

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:

C

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 14 × 8 = 7 × 8 = 56 in² → C

Answer:

C

Step-by-step explanation:

Since the figures are congruent then corresponding angles are congruent.

Then ∠ X = ∠ R , that is

∠ X = 135° → C
