Answer:
AC = 32 units
Step-by-step explanation:
It looks like DE is half of AC, so to find the length of AC you would multiply the length of DE by 2.
DE = 5x + 6, so 2(5x + 6) = AC.
Distribute the 2 inside the parentheses.
Now make this value equal to the expression standing for AC, 12x + 8.
Subtract 10x from both sides of the equation.
Subtract 8 from both sides of the equation.
Divide both sides by 2 to solve for x.
Take this value of x and substitute it into the expression for the length of AC.
Multiply 12 and 2 together.
Add 24 and 8.
AC = 32 units
One friend shoud receive 1/4 nuts
1/4 is equivalent to 2/8
Answer:
x^2 +2x +4
x^2 +2x +(2/2)^2-(2/2)^2+4
(x+1)^2-1+4
(x+1)^2+3=0
(x+1)^2= -3
(x+1)= ±√-3
Since a negative number cannot be square rooted,
there are no solutions to this equation.
Hope this helps:)
Answer:
It means that when x = 3, y = 1, obviously when the first function expression takes 3, y = 1
Answer:
The correct answers are 1 and 4. Rectangle and square.
Step-by-step explanation:
A rhombus is a four-sided geometric figure, which has the main characteristic that these four sides are equal to each other. They generally have a diamond shape, with four vertices pointing towards the four cardinal points.
The square, for its part, is a special type of rhombus, where not only its four sides are equal but also its angles, since they are four right angles.
