Since the largest size of one of the dimensions is 10.5, it has to correspond with the long side of the card, the 5 in. side. To find the proportion of the sides, divide 10.5 by 5. Then, multiply the other side of the card by the quotient.
10.5/5 = 2.1
2.1 * 2 = 4.2
4.2in is the shorter side. Your question asks to round to the nearest tenths, the smallest place value of the answer is already the tenths place.
That would be (9x2 - 25 = (3x-5) (3x+5)
Answer:
135
Step-by-step explanation:
6 x 2.5 = 15/2 = 7.5 x 2 = 15
8 x 6 = 48 + 15 = 63
8 x 2.5 = 20 + 63 = 83
6.5 x 8 = 52 + 83 = 135
Answer:
148
Step-by-step explanation:
15-1 because of the first day of school
14*10
=140
+8
=148
(a−b)(a(2)+ab+b(2))
=(a+−b)(a(2)+ab+b(2))
=(a)(a(2))+(a)(ab)+(a)(b(2))+(−b)(a(2))+(−b)(ab)+(−b)(b(2))
=2a2+a2b+2ab−2ab−ab2−2b2
=a2b−ab2+2a2−2b2
