Answer:
Area will be 2(lb + bh + hl)
So 2*(12*9 + 9*4 + 4*12)
384 sqft
The degree of a monomial is the sum of its exponents
4x^7y^3
exponents are 7 and 3
degree is : 7 + 3 = 10
Let's solve your system by substitution.
2x−2y=−4;2x+y=11
Rewrite equations:
2x+y=11;2x−2y=−4
Step: Solve2x+y=11for y:
2x+y=11
2x+y+−2x=11+−2x(Add -2x to both sides)
y=−2x+11
Step: Substitute−2x+11foryin2x−2y=−4:
2x−2y=−4
2x−2(−2x+11)=−4
6x−22=−4(Simplify both sides of the equation)
6x−22+22=−4+22(Add 22 to both sides)
6x=18
6x/6 = 18/6
(Divide both sides by 6)
x=3
Step: Substitute3forxiny=−2x+11:
y=−2x+11
y=(−2)(3)+11
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5

Answer:+3i or -3i
Step-by-step explanation:
±√(-36)=+√(-36) or -√(-36)
+√(-1)×√(36) or -√(-1)×√(36) √(-1)=i
+i×6 or -i×6=+6i or -6i
Dividing by 2 we get
+6i/2 or -6i/2=+3i or -3i
