Simplify the expression. 3t(t - 5) + 6t to the 2nd power
Nadusha1986 [10]
<span>: 2s + 3t = 28, 2s = 28 - 3t s = 14 - 3t/2 Substitute s into second equation 5s + 6t = 61, 5(14 - 3t/2) + 6t = 61, 70 - 15t/2 + 6t = 61, 70 - 3t/2 = 61, 3t/2 = 9, t = 6. We can then substitute t back into first equation: 2s + 3t = 28, 2s + 3 * 6 = 28, 2s = 10, s = 5. So the final answer is: s = 5 t = 6</span>

A rectangular lawn measuring 8m by 5m is surrounded by a flower bed of uniform width. The combined area of the lawn and the flow
Fed [463]

Answer:

10.68 m

Step-by-step explanation:

<u>Step 1: Area of flower bed</u>

<em>Uniform width means that all sides are the same which makes it a square.</em>

Area of flowerbed = L²

<u>Step 2: Area of rectangular lawn</u>

Area of rectangular lawn = Length x width

Length = 8m

Width = 5m

Area of rectangular lawn = 8 x 5

Area of rectangular lawn = 40m

<u>Step 3 : Calculate the width of the flower bed</u>

Combined Area = 154 m²

Area of rectangular lawn + Area of flower bed = Combined Area

40 + L² = 154

L² = 154

L = √114

L = 10.68 m

Therefore, the width of the flower bed is 10.68 m
