Answer:
B. 175 square cm
Step-by-step explanation:
Area of the figure = Area of parallelogram + Area of square + Area of triangle
Area of parallelogram = (base x height)
= (14 x 5)
= 70 
Area of square = (length x length)
= (7 x 7)
= 49
Area of triangle = (
base x height)
= ( x 16 x 7)
= 56
Area of the figure = 70+ 49 + 56
= 175
The area of the figure is 175 .
I went outside one night late, when i saw something in the street to my town. It was october 29th very close to halloween and very spooky. I felt shivers down my back. I felt like there was something floating around me. It wouldnt stop, or leave me alone. I went back to bed and kept waking up with a cold sweat..... To BE CONTINED.
I hope this helped and is up to your standards.
Have a nice day if this works for you please give me a heart.
Answer:
C
Step-by-step explanation:
i think c
not entirely sure
2x+y = -5. Solve this for y. We get y = -2x - 5. Find y^2: 4x^2 + 20x + 25. Substitute 4x^2 + 20x + 25 for y^2 in the first equation:
x^2 + 4x^2 + 20x + 25 = 25
Then 5x^2 + 20x = 0, so that x = 0. Subst. 0 for x in the 2nd eqn and find the value of y. Write your solutions as shown above: ( , ) and ( , ).
Distributive property
a(b+c)+ab+ac
a(b-c)=ab-ac
(6z^2-4z+1)(8-3z)
move for nicety
(8-3z)(6z^2-4z+1)
distribute
8(6z^2-4z+1)-3z(6z^2-4z+1)=
48z^2-32z+8-18z^3+12z^2-3z=
-18z^3+48z^2+12z^2-32z-3z+8=
-18z^3+60z-35z+8
