Answer:
n1=1,n2=4
Step-by-step explanation:
first divide both sides by 6 of the equation
=n^2-3n=4
n^2-3n-4=0..move the constant to the outerside
n^2-3n-4=0...write -3 as a difference
n^2+n-4n-4=0
factor out n
n×(n+1)-(4n-4)=0
nx(n+1)-4(n+1)=0
(n+1)×(n-4)=0
=n(+1=0)work out
n-4=0
n=-1
n-4=0
now solve for n
and the answer will be ;n1=-1,n2=4
Answer: 2
Step-by-step explanation: add 10 to both sides so -10+10=0 and -6+10=4
then you have 2x=4 simplify
Given that the triangle ABC is dilated by a scale factor of 1.25 to form the new triangle PQR, the dimensions of PQR will be as follows;
AB corresponds to PQ, but the length of AB=5 units, the length of PQ will be:
PQ=5*1.25=6.25 units
BC corresponds to QR, but the length if QR=4.2 units, the length of QR will be:
QR=4.2*1.25=5.25 units
lastly,
CA corresponds to RP, but CA=4 units, therefore RP will be:
4*1.25=5 units
