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
<span>C is the correct answer. When working with powers and bases, the base must be a number between 1 and 10. In this case, the number 1.347 is the only one to fit that definition. 1,000 is 10^3, so the full expansion would be 1.347 * 10^3.</span>
AC=64
CF=32
DF=28
this should be right:)
