the answe is 10.30
Step-by-step explanation:
im also from k12 lol
Answer:
12
Step-by-step explanation: we will use pathogorean theorem because there is a right triangle. a^2+b^2=c^2
We know BE=9 we need AE to find AB
You can make another triangle on the end. AD=28 - 12 (BC) = 16
16/2 = 8 so AE= 8
8^2+9^2=c^2
145=c^2
Square root of 145=c
C=12.04
Answer:
(x+5)²+(y-4)²=17
Step-by-step explanation:
I think it's safe to assume that the (-5,4) coordinate is in the center
To find the x and y coordinate just flip the signs
which means it would look like
(x+5)²+(y-4)²=?
the question mark is equal to the raidus squared
to find the radius use the distance formula
√((-4+5)²+(8-4)²)= 4.123106
square this to get 17
the final answer is then
(x+5)²+(y-4)²=17
To evaluate the given expression, we need the values of each variable and substitute these values to the expression. Then, go on with the operations involved.
<span>4x - y - 2z
4(-2) - (3) - 2(-2)
-8 - 3 + 4
-7</span>
The answer is the fourth choice
Because when u replace the values for x in the equations, it satisfies the inequality
