Answer:
(x-4)(x+5)
Step-by-step explanation:
Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)
Answer:
y=mx+b
Step-by-step explanation:
You would definitely want to memorize this important formula because you'll see this slope intercept form often in your Algebra I class, where m=slope and b=y-intercept.
Hello :
<span>(x - 3)² + y² = 7²
the center is : A(3 , 0 ) and radius r = 7
the </span> point D is on the interior if : AD <span>< 7
</span>the point D is on the exterior if : AD > 7
the point D is circumference of the circle if :AD = 7
Answer: D
Step-by-step explanation:
So we find what's called the GCF or greatest common factor
firest we find teh factors and group the like ones
40=2 times 2 times 2 times 5
20=2 times 2 times 5
we see a common set of numbers which is in both which is 2 times 2 times 5=20
biggest number that can go into both 40 and 20=20
