Answer:
here you go.
Step-by-step explanation:
The diagonal is the hypotenuse of a rectangular triangle.
So:
d2=l2+w2
132=169=(x+7)2+x2=x2+14x+49+x2→
2x2+14x−120=0→x2+7x−60=0
A simple quadratic equation resolving into:
(x+12)(x−5)=0→x=−12orx=5
Only the positive solution is useable so:
w=5andl=12
Answer:
Step-by-step explanation:
When negatively charged rubber rod is brought close to sphere X it induces positive charge on sphere and simultaneously negative charges is induced in the sphere opposite to the side of rod .
At the same time Sphere Y is touched to the sphere X , this causes the negative charge to shift to the sphere Y with the help of negative charged rod which repels the electrons to sphere Y.
When rubber rod is moved far away from X and Y then final charge possessed by X and Y spheres are
X:Positively charge
Y:Negatively charge
Answer:
y=1x-4
Wait sorry I did it wrong the first time lol.
In standard Form, it should be 4x-4y=16
Step-by-step explanation:
yes yes hand me brain

false
Step-by-step explanation:
Answer:
1109
Step-by-step explanation:
you can subtract the terms to see the difference between them
-11-(-27)=16
The sequence is increasing by 16
you can plug that 16 in the formula for d
a_n=a_1+(n-1)d
a_n=a_1+(n-1)16
n represents the term you want to find in this case the 72nd
a sub 1 is the first term of the sequence in this case -27
a_72=-27+(72-1)16
a_72=-27+(71)16
a_72=-27+1136
a_72=1109
