If you need the sum than here is an equation for it 7x3= 21
Hi there!
3c + 2d = 2 for d = 4
3c + 2(4) = 2
3c + 8 = 2
Subtract 8 to both sides
3c + 8 - 8 = 2 - 8
3c = -6
Divide both sides by 3
3c/3 = -6/3
c = -2
I hope I helped!
Answer:
<u>Square</u>
Step-by-step explanation:
Requirements that make a square, a square;
- Four sides
- Congruent angles (all 90°)
- Opposite sides are congruent/the same.
- Opposite sides are also parallel because the lines of a square do not intersect.
If this shape is trapezium
m (<D) = m (<C)
since AB parallel to CD
m (<C) + m (<A) = 180°
m (<C) = 180 - 125 = 55°
m (<D) = 55°
