A rectangular patio is 9 ft by 6 ft. When the length amd width are increased by the same amount, the area becomes 88 sq ft. Ging

SpyIntel [72]

( 6 + x)(9 + x) =88

54 + 15x + x^2 = 88

x^2 + 15x - 34 = 0

(x + 17)(x - 2) = 0
using zero product property:-
x + 17 = 0 or x - 2 = 0 giving:-

x = -17 , x = 2

x is the amount that the length and width are increased by.

x = -17 is negative and doesn't make sense in this context and can be ignored; so the amount of increase is 2 feet.

The population of a town increases at a rate of 5% every year. The population of this town was 10,400 in 2017. What will the pop

galben [10]

Answer:

The population of the town in 2020 will approx. be 12,039.

Step-by-step explanation:

The initial population in the year 2017 = 10,400

Increase in population every yea r = 5%

Now, 5% of 10, 400 = $\frac{5}{100} \times 10, 400 = 520$

Hence, the population in the year 2018 = 10,400 + 520 = 10,920

Now, in the year 2019

5% of 10, 920 = $\frac{5}{100} \times 10, 920 = 546$

Hence, the population in the year 2019 = 10,920 + 546 = 11,466

Now, in the year 2020

5% of 11,466 = $\frac{5}{100} \times 11,466 = 573.3$

or, the population in the year 2020 = 11,466 + 573.3 = 12,039.3

The population of the town in 2020 will approx. be 12,039.

zvonat [6]

Answer:

Difference in temperature = 25°C

Step-by-step explanation:

Given:

Temperature 1 = -51°C

Temperature 2 = -76°C

Find:

Difference in temperature

Computation:

Difference in temperature = Temperature 1 - Temperature 2

Difference in temperature = -51°C - [-76°C]

Difference in temperature = -51°C + 76°C

Difference in temperature = 25°C
