When x = 2
3x^2 = 3*4 = 12
12-4 = 8
C. is the answer
To find a perimeter of any shape you just need to add together all the sides of the shape.
For example: /_\ (pretend this is a triangle)
If each side of the triangle is 5 cm, then 5+5+5=15 cm (or you can do 5*3=15 cm)
The perimeter of the triangle is 15 cm.
Hope I helped!(:
7y^2 + 10y + 3
7y^2 + 7y + 3y + 3
(7y^2+7y) + (3y+3)
7y(y+1) + 3(y+1)
(7y+3)(y+1)
So the final answer is <span>(7y+3)(y+1)</span>
Answer:

Step-by-step explanation:
To find the third angle of a right triangle you add 90 to the angle and subtract from 180
so angle E is 180-(55+90)=35 so the triangles have 2 angles are the same so
