7a
x2 + 4x + ax + 4a
x2 + ax + 4x + 4a
x (x + a) + 4 (x + a)
:(x + 4)(x+a)
7d
x2+2x-ax-2a
x2-ax+2x-2a
x (x-a)+2 (x-a)
:(x+2)(x-a)
7h
x2-2bx-5x+10b
x2-5x-2bx+10b
x (x-5)-2b(x-5)
:(x-2b)(x-5)
Definition of an equilateral triangle: A triangle with the exact same sides and angles, which is 60°
<em>5 more than twice a number:</em>
Let the number be x:
2x + 5
<em>Since it is an equilateral triangle, multiply that by 3:</em>
3(2x +5) = 6x + 15
The perimeter is (6x + 15) inches.
