Answer:
x^3 + 4x^2 - 7x - 10
Step-by-step explanation:
To solve this we're going to use Polynomial multiplication, starting by multiplying (x-2)(x+1) = x^2 - 2x + x - 2 = x^2 - x - 2. Next, we will multiply (x^2 - x - 2)(x+ 5) = x^3 + 5x^2 -x^2 - 5x -2x -10 = x^3 + 4x^2 - 7x - 10.
Answer:
136 square cm
Step-by-step explanation:
Area of rectangle = 18x7=126 square cm
Area of triangle = 1/2x(11-7)x(18-13) = 1/2(4)(5) = 10 square cm
126+10 = 136 square cm
Answer:
x=−7/5and y=−6/5
Step-by-step explanation:
Step: Substitute−2x−4foryiny=3x+3:
y=3x+3
−2x−4=3x+3
−2x−4+−3x=3x+3+−3x(Add -3x to both sides)
−5x−4=3
−5x−4+4=3+4(Add 4 to both sides)
−5x=7
−5x
−5
=
7
−5
(Divide both sides by -5)
x=−7/5
Answer:
70%
Step-by-step explanation:
49/70 = 0.7
0.7*100 = 70%
I think it is
(1/3)+1+3+9+27+81+243
=364/1/3
=1093/3
