Answer:(k+1)(2K+7)
Step-by-step explanation:
Using the quadratic formula
X=-b±-√b^2-4ac/2a
ax^2+bx+c=0
2k^2+9k+7=0
In this case a=2,b=9,c=7
-9+-√9^2-4(2)(7)/2(2)
(-9+√25)/4=-9+5/4=-1
(-9-√25)/4=-14/4 =-7/2
X=-1,X=-7/2
So (K+1)(k+7/2)
So (k+1)(2k+7)
Answer:
x=2y−47x
Step 1: Add 47x to both sides.
x+47x=−47x+2y+47x
48x=2y
Step 2: Divide both sides by 48.
48x
48
=

C. 196 sq. In.
Multiply 4×7×7 To find the surface area.
A= (-4,2)
The x value (-4) stays the same when reflected over the x-axis, so only the y-value gets reflected and therefore changed.
The resultant coordinate is (-4,2)
968.58=200.78+76.78w
-200.78
767.8=76.78w
/76.78
=10w
