say, one angle is x

 

Other angle = x +40

 

x + x + 40= 180

2x = 140

x = 70

 

One angle = 70

 

Other angle =110

(Hope this helps)

Answer:

25 * 65 degrees

Step-by-step explanation:

Complementary angles = 90 degrees

90-40=50

50/2=25

25+40=65

65+25=90

Which of the following is not a correct form of the quadratic function?
aleksklad [387]

Answer:

The squared form is not a correct form of the quadratic function.

Step-by-step explanation:

Given some forms of quadratic equation. we have to choose the form which is not correct of the quadratic equation.

As the general form and the standard form of quadratic equation is

y=ax^2+bx+c where a,b and c are constant.

Also, the vertex form is

y=m(x-a)^2+b where (a,b) is vertex.

Only the three forms of quadratic equation exist. No other form like squared form exist.

Hence, the squared form is not a correct form of the quadratic function.

Im not really good at seventh grade math I need some help!!​
Darina [25.2K]

Answers:

1/2a= 8

Multiply by 2/1 on both sides

1/2(2/1)a= 8(2/1)

Cross out 1/2 and 2/1 equals to a

a= 16

4n= 32

Divide by 4 for both sides

4n/4= 32/4

n= 8

3x= 36

Divide by 3 for both sides

3x/3= 36/3

x= 12

m/3= 2

Multiply by 3/1 for both sides

3/1*m/3= 2(3/1)

Cross out 3/1 and 3 becomes m

m= 6

x-8= 12

Move -8 to the other side. Sign changes from -8 to +8

x-8+8= 12+8

x= 20

48= 3k

Divide by 3 for both sides

48/3= 3k/3

k= 16

13/b= 0

Multiply by 1/13 for both sides.

13/b( 1/13)= 0(1/13)

b= 0

39= 13y

divide by 13 for both sides

39/13= 13y/13

y= 3
