Answer:

B

Step-by-step explanation:

ac =5x

cb=7x

(5x×5x)+ (5 +7)^2 = 7x^2

25x^2+144=49x^2

x=kök 6

ac =5kok 6

(5kok6)×12÷2= 30 kök 6

Answer:

The value of x is 7 cm.

Step-by-step explanation:

we can see that there are two triangles. smaller triangle and larger triangle.

Answer:

17

Step-by-step explanation:

Answer:

a=17

Step-by-step explanation:

When an equation says +(-) like this one, all you have to do is subtract :)

Knowing that if you rewrite this you get a= 21-4, which is 17!

Answer:

I think it's -180

Step-by-step explanation:

He keeps descending -15 feet every 1 minute

1 x -15 = -15

2 x -15 = -30

12 x -15 = -180

Answer:

2(4x+3)

Step-by-step explanation:

We need to find what is the most common between 8x and 6. The only number here is 2 that is common between them.

That will be on the outside of the bracket.

So if we divide 2 from both terms.

8x ÷ 2 = 4x

6 ÷ 2 = 3

Let's put it all together.

2 first.

Our x term and 3 in brackets.

2 (4x+3)

There we go!

Answer:

Yes I believe so because the interiors of a triangle always add up to 180 degrees meaning the outside mustn't follow this same rule hop this helps!

Step-by-step explanation:

Answer:

Lets assume you have a triangle ABC with a straight horizontal line at the bottom say line segment CD. In order for the exterior angle to be greater than 180 it must be a exceed rad Pi which mean it is impossible for an exterior angle to exceed the 180 rule

The function that best fits the data is  [tex]y=4^x[/tex]

"The function of the form [tex]y=ab^x[/tex] where a, b are real numbers and a ≠ 0 "

For given question,

The scatter plot with data points that form an upward curve staring at the origin and continuing to the right.

The graph represents an exponential function.

At (0, 1),

[tex]\Rightarrow 1=ab^0\\\Rightarrow a=1[/tex]

At (1, 4) we have,

[tex]\Rightarrow 4 = ab^1\\\Rightarrow 4=(1)b\\\Rightarrow b=4[/tex]

So, we have exponential function of the form [tex]y=4^x[/tex]

Hence, the function that best fits the data is  [tex]y=4^x[/tex]

Step-by-step explanation:

I've written my working in the picture. I hope it's clear. :,)

I've expanded the brackets, simplied the fractions before simplifying them again, having found the common denominators of the constants and x terms.

Answer:

This function is an even-degree polynomial, so the ends go off in the same directions, just like every quadratic I've ever graphed. Since the leading coefficient of this even-degree polynomial is positive, the ends came in and left out the top of the picture, just like every positive quadratic you've ever graphed. All even-degree polynomials behave, on their ends, like quadratics.

Answer:

6n - 1.

Step-by-step explanation:

Arithmetic sequence.

a1 = 5, d = 6.

nth term = a1 + d(n - 1)

= 5 + 6(n - 1)

= 5 + 6n - 6

= 6n - 1.

Answer:

X=3

Step-by-step explanation:

=> 4(3x+2)=44

=> 12x=44 - 8 [Transpose 8 of L.H.S to R.H.S]

=> 12x= 36

=> x= (3)

Answer:

x= 20

AD= 23

DC= 23

AC= 46

Answer:

y=70

x=55

Step-by-step explanation:

In an equilateral triangle, all the angles measure 60 degrees. Knowing this, we can set the following equations:

[tex]60=y-10\\60=x+5[/tex]

[tex]60=y-10[/tex]

Add 10 to both sides

[tex]60+10=y-10+10\\70=y[/tex]

[tex]60=x+5[/tex]

Subtract both sides by 5

[tex]60-5=x+5-5\\55=x[/tex]

I hope this helps!

Answer:

x is 55° & y is 70°.

Step-by-step explanation:

This is an equilateral triangle.

In an equilateral triangle all sides are 60°

So,

1) x+5 = 60

x = 55°.

2) y-10 = 60

y = 70°.

Answer: x is 55° & y is 70°.

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough

Step-by-step explanation:

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough

=3 2/3 - 1 3/4

changing to improper fraction to make it easier to subtract

11/3 -7/4 = (44- 21)/12 = 23/12  =  1  11/12  cups of flour
