Answer:
26.
Step-by-step explanation:
Given, BD is a median. As it divides the AC equally, that's why it will AD=CD. Given, AD= 6x+10 and CD= 2x+12
Now, AD= CD
or, 6x+10=2x+12
or, 6x-2x= 12-10
or, 4x= 2
or, x= 1/2
So the value of x is 1/2. As BD divided AC equally, both AD and CD will be equal and AD+CD= AC.
So, 6x+10+2x+12= AC
or, 8x+22= AC
or, 8 X (1/2) + 22= AC
or, 4+22 = AC
or, AC= 26.=
Answer:
Step-by-step explanation:
y = a(x - p)^2 + q....the graph of the parabola represented by this quadratic function has an axis of symmetry represented by the equation x = p.
f(x) = (x + 3)^2 - 4.....the axis of symmetry is in the p position of the formula used above.....so the axis of symmetry is -3, therefore, ur equation is x = -3
but before u do anything, u have to make sure ur quadratic equation is in vertex form...in the form of y = a(x - p)^2 + q
101.15
Explanation:
140 x 7.25% = 10.15
140 x 35% = 49
Then we add the tax and subtract the sale :
140 + 10.15 - 49 = 101.15$
Hope it’s right
Best luck with your studying
Answer:
135
Step-by-step explanation:
we know that straight angle is 180 degree and there is acute angle which is 45 degree now 180-45=135
Maybe you can do 8 divided by 2 would equal 4 or you can do equations that equal 8.
