Answer:
B. 50
Step-by-step explanation:
AD=AB so 13=AD also.
DE=12 so EB=12 also.
When you add DE and EB together you get DB= 24
There are 2 legs and 1 hypotenuse to a triangle. Your legs are a+b and you hypotenuse is c.
AD=a(13) AB=b(13) DB=c(24)
P= a+b+c
so you add 13 + 13+ 24
Answer:x=−9
Step-by-step explanation:
Apply the distributive property.
3 x + 3 ⋅ 1 − 2 x = − 6
Multiply 3 by 1
.
3 x + 3 − 2 x = − 6
Subtract 2x from 3x.
x + 3 = − 6
Move all terms not containing x to the right side of the equation.
Subtract 3 from both sides of the equation.
x = − 6 − 3
Subtract 3 from − 6 .
x = − 9
Answer: 8
Step-by-step explanation:
we know the area of a circle is
A=π r²
50.24= 3.14* r²
50.24/3.14=r^2
16=r^2
r=sqrt 16=4
diameter is 2r=2*4=8
Answer:
i believe it is B, havent used that skill in a bit !!
The given equation is ⇒⇒⇒ 2y - 4x = 6
∴ 2y = 4x + 6 ⇒ divide all the equation over 2
∴ y = 2x + 3 and it can be written as ⇒⇒⇒ y - 2x = 3
The last equation represents a straight line with a slope = 2 and y-intercept = 3
To construct a system of equations with definitely many solutions and the equation ( 2y-4x=6 ) is one of the equations, the other equation must have the same slope and the same y-intercept.
so, the general solution of the other equation is ⇒ a ( y - 2x ) = 3a
Where a is constant and belongs to R ( All real numbers )
The system of equations which has definitely many solutions is consisting of <u>Coincident lines.</u>
