Answer:x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':
Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7
Answer:
x=160°
since the sum of angles of the shape measures 540°
by summing up the values, we have
3x=480 divide both sides by 3
x=160°
Answer: x²+8x+16
Step-by-step explanation:
(x+4)^2=(x+4)(x+4)
Now use distributive property to expand (x+4)(x+4):
(x+4)(x+4)=x²+4x+4x+4(4)
x²+4x+4x+4(4)=x²+8x+16
There are 16 cups in a gallon, if you multiply 16 by 3, you get 48. So, there are 3 gallons of milk in the Chef's adjusted recipe.
Hope this helped!
