Answer:
x^2 -4x -21
Step-by-step explanation:
Here, we want to write a quadratic polynomial
We have the sum as -4
Let us have x as the variable
so the sum of the variables is -4x
while the product is -21 x^2
Two factors of 21 that can work here is -7x and 3x
So we have
x^2 - 7x + 3x -21
= x^2 -4x -21
If this is being simplified the answer is 116760000000
Answer:
∠7 = 81°
Step-by-step explanation:
∠1 = ∠7
3x + 18 = 2x + 39
3x - 2x = 39 - 18
x = 21
∠7 = 2x + 39
∠7 = 2(21) + 39
∠7 = 42 + 39
∠7 = 81°
