Answer:
18x + 16
Step-by-step explanation:
2 x length + 2 x width = perimeter
2(5x + 2) + 2(4x + 6)
= 10x + 4 + 8x + 12
= 18x + 16
Answer:
A real solution in algebra is simply a solution to an equation that is a real number.
for example
If y>0, then x2 = y has two real solution or roots. x = ±√y
If y=0, then x2 = y has one real solution.
Answer:
A. x=10
B. x=-19
C. x=53
D. x=-1/28
Step-by-step explanation:
A.
2x+3=23
2x=20
x=10
B.
-3(x+9)=30
x+9=-10
x=-19
C.
0.75x-12.75=27
0.75x=39.75
x=53
D.
1/2x+6=-8
1/2x= -14
1=-28x
x=-1/28
Answer - 17

Answer: (3x+2)(x+4)
Step-by-step explanation:Explanation:
3x2+10x−8
first multiply
3
with −8
and we get −24
then find two numbers that if we add or subtract we get
+10
and if we multiply we get
−24
and the numbers are
+12
and
−2
then we place those numbers as follow :-
3x2+12x−2x−8
then we group them
(3x2+12x)(−2x−8)
now take the common factor out.3x(x+4)−2(x+4)
then group the numbers outside of the brackets
(3x−2)(x+4)
