Mmk so u take 14^2 and 48^2
14*14= 196 48*48= 2304
196+2304= 2500
than find the square root of 2500
√2500
so ur answer is 50
T is greater than -15 because numbers after -15, like -16... are less than -15, so when its decreasing it gets lower. Since the questions says the temp stayed above -15, that means the temp could be -14...-13 and so on.
Answer:
substract.
Step-by-step explanation:
eg. 5 before 17 = 17-5
so 5 before 17= 12
same for others
Here you go!
3n-4=14
+4 +4
3n=18
(Divide both sides by 3)
n=6
<span>Let the extension of the length and width be x.
The new dimensions are: Length = 8+x
Width =3+x
Area = 104 ft squared
Area of a rectangle = Length x Width
Therefore,
(8+x)(3+x) = 104
x^2 +11x +24=104
x^2 +11x +24-104=0
x^2 +11x-80=0
Factorize using splitting the middle term method.
X^2 +16x-5x-80=0
x(x+16)-5(x+16)=0
(x-5)(x+16)=0
either x-5 = 0 or x+16=0
x=5 or x=-16
length and width measure cannot be negative.
Therefore, the extension of the length and width is 5 feet each.</span>
