Area of square = l²
Perimeter of square = 4l
According to the question,

Using zero product property,
Either,

Or,

Since length can't be negative,
the length is 9
Answer:
Step-by-step explanation:
steps are below
step 1
y^3-8y^2+19y=12 equation
step 2
y^3-8y2+19y(-12)=12(-12) minus 12 from both sides
y^3-8y^2+19y-12=0
step 3
(y-1)(y-3)(y-4)=0 add brackets
step 4
(y-1)(y-3)(y-4)=0 factor
step 5
y-1=0 or y−3=0 or y-4=0 set them equal
Answer:
y=1 or y=3 or y=4
Answer:
r equals start fraction cap a minus p over p t end fraction
Step-by-step explanation:
Subtract the term non containing r, then divide by the coefficient of r.

The first option is your answer.
Sigma notation is just a fancy way to shorten a sum of a series of numbers using a set equation. The "n =" tells you where to start in the sequence and the top number tells you where to stop.
Answer:
Answer to question 8 is : Area =1017.88 and Circumference =113.1
Answer to question 9 is: Area =490.87 and Circumference =78.54
Step-by-step explanation:
8. i just did πr2for area and for circumference i did 2πr which is just the equation to find each
9.i found that half of the diameter is 12.5 so i did πr2 to find the Area i filled in the radius and pai and 2πr for circumference filled in the pai and radius
oh also round it if u want
plz give me brainliest and rate it that u and goodluck
