What Is The Answer To This?

Answers

Answer 1

Answer:

true

Step-by-step explanation:

5(1+2x)= 5 +10x =10x + 5

Answer 2

Answer:

Yes, they are eqivelant.

Step-by-step explanation:

5(1+2x) and 10x+5

The first step is to set them equal to each other, to see if they are equivelent.

5(1+2x) = 10x+5

Distribute the 5 to both terms in the parentheses by multiplying.

5(1) + 5(2x) = 10x +5

5 + 10x = 10x +5

The communative property of addition proves that these are equal.

(A) Two acute angles add to an obtuse angle
(B) Two adjacent angles make a line
(C)Two obtuse angles are supplementary
Decide if each statement is always, sometimes, or never true.
I said never for the first one I’m new to geometry and I’m a freshman I’m taking notes along the way so whatever information you have for me will help!❤️

Answers

Answer:

(A) Two acute angles add to an obtuse angle

It's sometimes because for example if you take two acute angles

one is 30 and other is 20

they add to 50 and not greater than 90 so it can be sometimes greater but not always

(B) Two adjacent angles make a line

Its also sometimes because a line means it should be 180 degrees so two adjacent angles can out always be equal to 180 that is a line

(C)Two obtuse angles are supplementary

It's Never true because obtuse angles start from 90 so if you take 91 also and other 91 too so if we add them up  that will be 182 not 180

as we know 180 = supplementary angle that's why

find the measure of the angle that is 12° more than two times its supplement

Answers

Answer:

56 and 124

Step-by-step explanation:

Sum of two supplementary angle = 180

Let the first angle be x

Second angle = 2x + 12

2x + 12 + x = 180

3x + 12 = 180

3x = 180 - 12

3x = 168

x = 168/3

x = 56

2x + 12

2(56) + 12

112 + 12

[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]

[tex]\text{then the perimeter can be expressed as}[/tex]

[tex]2(24+x)=72[/tex]

[tex]24+x=36[/tex]

[tex]x=12[/tex]

[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]

Answer: Solution,

length (l) = 24 cm

perimeter (p)= 74 cm

Area (A) = ?

we know,

P = 2(l + b )

74 = 2( 24 + b)

74 = 48 + 2b

2b = 74 - 48

2b = 26

b= [tex]\frac{26}{2}[/tex]

b = 13

now,

A = l*b

   = 24 * 13

   = 312 cm square

Therefore, the area of the rectangle is 312 cm square.

add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate

Answer:

147

Step-by-step explanation:

If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Answers

Answer:

Step-by-step explanation:

1) x² - 8x + 5 = 0

2) No subtract 5 from both sides

x² - 8x + 5 - 5 = 0 - 5

x² - 8x  = -5

3) Now find (8/2) = 4. Add 4² = 16 to both sides

x² - 8x + 16 = -5 + 16

x² - 8x + 16 = 11

4) (x - 4)²  = 11

5) Take square root both sides

x - 4 = ±√11

x = 4 ±√11
