Answer:

A. 108

Step-by-step explanation:

This is because 180(n-2)=180(5-2)=180(3)=540 in the whole pentagon. Since there are 5 angles, divide: 540 divided by 5= 108

What is the solution of this equqtion? 4+ 1/4 w=6​
ale4655 [162]

Answer:

w = 8

Step-by-step explanation:

4+ 1/4 w=6​

Subtract 4 from each side

4-4+ 1/4 w=6​-4

1/4w = 2

Multiply each side by 4

4* 1/4 w=2*4

w = 8

Evaluate the expression using the order of operations and rules for signed numbers. 6.8(6.7 – 7.2) – 2(4.6 + 1.2) =
Schach [20]

Answer:

-15

Step-by-step explanation:

6.8(6.7 – 7.2) – 2(4.6 + 1.2)

The first step in PEMDAS is to do whatever's in the parenthesis. So, this would be the 6.8 bit.

6.8 times 6.7 is 45.56 and then 6.8 times 7.2 which is 48,96

Now we can also do the second set of parenthesis. 2 times 4.6 is 9.2, and 2 times 1.2 is 2.4

The equation now reads- (45.56 - 48.96) - (9.2 + 2.4)

All we have to do is evaluate what's in the parenthesis, the first set equals -3.4 and the second set equals 11.6

So, now our expression reads, -3.4 minus 11.6 which equals -15

Given the function ƒ(x) = x 2 - 4x - 5
nordsb [41]

Answer:

Zeros of the given function are x=5 and x=-1.

Step-by-step explanation:


f(x)=x^2-4x-5

f(x)=x^2+1x-5x-5

f(x)=x(x+1)-5(x+1)

f(x)=(x-5)(x+1)

To find zeros, we need to set f(x)=0

0=(x-5)(x+1)

0=(x-5) or 0=(x+1)

0=x-5 or 0=x+1

5=x or -1=x


Hence zeros of the given function are x=5 and x=-1.


We can plug some random numbers like x=0,1,2,... into given function to find few points then graph those points and join them by a curved line.

That will give the final graph as attached below:

for x=0,

f(x)=x^2-4x-5

f(0)=0^2-4(0)-5

f(0)=0-0-5

f(0)=-5

Hence first point is (0,-5)

Similarly we can find more points.

How many triangles can you construct with the angle measures of 50, 70, and 100?
lidiya [134]

Answer:

0

Step-by-step explanation:

You can't construct any triangles with those angles. Because when you add all the angles of a triangle, it has to add up to 180. But when we add 50,70, and 100, it equals 220. So you can't construct any triangles.

Hope this helps.<em> (If it does, please mark me brainliest)</em>
