The answer to this is 65.

Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180.

First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180.
180-148=32. x=32.

Then we plug that in the expression for angle a.
2x+1 becomes 2(32)+1
2*32=64
64+1=65.
a=65

The zeros of a function are the values of for which the function is equal to zero. Enter a number in each blank to make true sta

Answer:

Here we want to complete the blank to make the equality true:

( ) = (2 - 6)*(-4)

The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:

x = (2 - 6)*(-4)

We just need to find the value of x.

Then let's solve the right side:

x = (2 - 6)*(-4) = (-4)*(-4)

Remember the rule of signs:

(-)*(-) = (+)

x = (-4)*(-4) = 4*4 = 16

Then we need to complete the blank with the number 16

(16) = (2 - 6)*(-4)
