-5(p+3/5)=-4 what is the answer

skelet666 [1.2K]

Answer:

-5(p+3/5)=-4 what is the answer

The answer is P = 1/5

Step-by-step explanation:

from the question -5(p+3/5)=-4 applying the law of BODMAS we will use -5 to open the bracket

we have [-5(p) + -5×3/5] = -4

-5p - 3 =-4

collecting the like terms

we have; -5p = -4 + 3

-5p = -1

divide both sides by -5

we have; -5p/-5 = -1/-5

the minus sign cancels out and we have

p= 1/5

check your answer by sloting the value of p into the question -5(p+3/5)=-4

-5(1/5 + 3/5) = -4

-4=-4

The figure the Floor Plan of a balcony ,it consists of △ABC and semi-circle ,

ivanzaharov [21]

Step-by-step explanation:

(a) In right triangle ABC,

$AC^2 =AB^2 +BC^2 \\ = {12}^{2} + {5}^{2} \\ = 144 + 25 \\ = 169 \\ AC = \sqrt{169} \\ \therefore \: AC = 13\: m \\ \\ AC \: is \: the \: diameter \: of \: semicircle \\ \therefore \: r = \frac{1}{2} \times AC = \frac{1}{2} \times 13 = 6.5 \: m \\ Circumference \:of \:semi-circle \\ C = \pi \: r = 3.14 \times 6.5 = 20.41 \:m\:$

Perimeter of Balcony = 12 + 5 + 20.41 = 37.41 m

(b) Area of balcony

$=\frac{1}{2}\times 12\times 5+\frac{1}{2} \pi r^2 \\\\=\times 6\times 5+\frac{1}{2} \times 3.14\times (6.5)^2 \\\\=30+\frac{1}{2} \times 3.14\times42.25\\\\= 30+\frac{1}{2} \times 132.665\\\\= 30 + 66.3325\\\\= 96.3325 \:m^2 \\\\\approx 96. 33\:m^2$
