<span> Norman window with a perimeter of 22 feet?</span>
Let's factor x^2−22x+121
The middle number is -22 and the last number is 121. Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks? We need two numbers that...
Add together to get -22
Multiply together to get 121
Can you think of the two numbers?
Try -11 and -11:
-11+-11 = -22
-11*-11 = 121
Fill in the blanks in
(x+_)(x+_)
with -11 and -11 to get...
(x-11)(x-11)
Answer: (x-11)(x-11)
Hope this helps!!!
Arc with endpoints that are the endpoints of a diameter is called a semicircle and has a measure of 180 degrees. Adjacent arcs are two arcs on the same circle which d<span>o not overlap and s<span>hare a common end point. Hope this answers the question.</span></span>
Answer: x = -1
Step-by-step explanation:
The problem is asking you the sum (+) of 3 times of a unknown number (let the unknown number be x) and 7, as in 3x + 7
According to the problem this expression is equal to 4,
3x + 7 = 4
1. Subtract 7 from both sides
3x = -3
2. Divide 3 on both sides
x = -1
Your final answer would be negative 1
Let length be l
and breadth be b
perimeter = 28
2(l+b) = 28
l + b = 14
l = 14 - b
area = 48
l x b = 48
(14 - b) b = 48
14b - b^2 = 48
b^2 - 14b + 48 = 0
b^2 -6b - 8b + 48 = 0
b( b - 6 ) - 8 ( b - 6) = 0
(b-8) ( b-6) = 0
so
either b = 8 or b = 6
if b= 8
l = 14 - 8 = 6
( not possible as length cannot be smaller than breadth)
so
breadth = 6
length = 8
