Step-by-step explanation:
the area is
length × width
increasing the length by 30% means multiplying the original length by 1.3.
increasing the width by 10% means multiplying the original width by 1.1.
so, the new area is (by using the old length and width)
length × 1.3 × width × 1.1 = length × width × 1.3×1.1 =
= old area × 1.3 × 1.1 = old area × 1.43
so, the area increases by 43%.
Answer:
perimeter = 40 feet
Step-by-step explanation:
side^2 = 100
side = 10
perimeter = 10 x 4 =40
The two numbers could be 8 and 9.
8×8=64 and 9×9=81.
81-64=17.
<u>Answer</u>
2,737,152a⁵b⁵
<u>Explanation</u>
(2a - 3b)¹⁰ = (2a)¹⁰ - 10(2a)⁹(3b) + 47(2a)⁸(3b)² - 144(2a)⁷(3b)³ - 212(2a)⁶(3b)⁴ + 352(2a)⁵(3b)⁵
The 6th term in this expression is 352(2a)⁵(3b)⁵
352(2a)⁵(3b)⁵ = 352 × 2⁵a⁵ × 3⁵b⁵
= 352 × 32 ×243 ×a⁵b⁵
= 2,737,152a⁵b⁵
