Answer:

2x^2-5x-12

Step-by-step explanation:

a rectangle has a length of 2x+3 and a width of x-4 find the area

------------

Area = length * width

-------------------------

A = (2x+3)(x-4)

---

A = 2x(x-4)+3(x-4)

---

A = 2x^2-8x+3x-12

---

A = 2x^2-5x-12

7x300=7x 3 hundres because in 300 hundreds there is 3 hundreds.I know that didnt make sense.so basically just look at the front number number its 3 so 3 hundreds but if your working with thousands and the front number is 5 its 5 thousands.I hope this was helpful.

Stewart said that 30-10p does not equal 5(2p-6) for any value of p. Do you agree with Stewart? Justify Stewart's answer, or expl

charle [14.2K]

Ya he is correct !

for any value of P, both can never be equal !
as, 5(2p-6) = 10p-30 .....so even if we put any value , negative or positive, (-30) can not be changed anyway !

thus 30-10p can never be equal to 5(2p-6) !!
