Answer:
x=3 or x=−9
Step-by-step explanation:
Step 1: Subtract 27 from both sides.
x2+6x−27=27−27
x2+6x−27=0
Step 2: Factor left side of equation.
(x−3)(x+9)=0
Step 3: Set factors equal to 0.
x−3=0 or x+9=0
x=3 or x=−9
Answer:
x=3 or x=−9
Answer: Second graph is the correct option.
Step-by-step explanation:
Since we have given that
![y=-2(2)x+2\\\\y=-4x+2](https://tex.z-dn.net/?f=y%3D-2%282%29x%2B2%5C%5C%5C%5Cy%3D-4x%2B2)
We will find the coordinate on y - axis first,
for coordinates on y-axis then x must be equal to 0.
so, put x=0,
![y=-4(0)+2\\\\y=0+2\\\\y=2](https://tex.z-dn.net/?f=y%3D-4%280%29%2B2%5C%5C%5C%5Cy%3D0%2B2%5C%5C%5C%5Cy%3D2)
So, according to this, Second graph has satisfied it.
Hence, Second graph is the correct option.

4. Check your answer and present the solution
Step-by-step explanation:
A picture can help you sort this out.
Draw point E on CD so that AE ⊥ CD. Then the distance DE is 8cos(60°) = 4, and the height AE is 8sin(60°) = 4√3. The length of CD is 8+2×4 = 16. The area of the trapezoid is the product of the height and the average base length:
... A = (b1 +b2)/2×h = (8 cm + 16 cm)/2×(4√3 cm) = 48√3 cm² ≈ 83.14 cm²
Answer:
x=-16
Step-by-step explanation:
