A is the awnser because it’s is saying 38 more
The sum of the angles of a quadrilaterals is 360 so 8s=360 s=45
All 45 45 90 triangles sides are equal to x, x, and xsqrt2. which is the biggest side. So here x(11) and x(11) are both given. the answer to the x shown on the triangle is xsqrt2
Answer:
So EASY
Step-by-step explanation:
Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
