What missing number would complete the factorization x^2- 7x + 10 = ( x - 5 ) ( x - ? )
a. 1
b. 2
c. 4
d. 5

For ax^2+bx+c if that is factored to (x+d)(x+e)
then de=c

so

-5 times ?=10
divide both sides by -5
?=-2

so then
(x-2)
?=2 because the negative is already there

B is answer

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
