Step-by-step explanation:
Answer:
75
Step-by-step explanation:
<h2>A=1/2h(a+b)</h2><h3> =10÷2=5(10+5)</h3>
=5×15
<h2> =75</h2>
Answer with factoring: 2(3y+4)
Answer with simplifying: 6y+8
Answer:
2.
4x^2 + 4 - 5x + x - 2x^2 + 8
= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)
= 2x^2 - 4x + 12
=> D is correct
3.
2x^2 + 6x - 7x + 8 - 3x^2 + 1
= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)
= -x^2 - x + 9
=> C is correct
4.
B is correct (4 and 3)
Hope this helps!
