Answer:

The correct answer is Option C . d -5

Step-by-step explanation:

Identity: (a + b)(a - b) = a² - b²it is given that,

it is given that,

(d - 5)(?) = d² - 25

LHS = (d - 5)(?)

RHS = d² - 25

we can compare this with the identity.

here, a = d and b = 5

therefore we can write and start with RHS

RHS = d² - 25 = d² - 5² = (d +5)(d - 5) = LHS

(d +5)(d - 5) = d² - 25

Therefore option C. (d- 5) is the correct answer.

Answer:

$a=250$

$b=10$

Step-by-step explanation:

$a=\frac{5x^2}{2}=\frac{5(10)^2}{2}=\frac{5(100)}{2}=\frac{500}{2}=250$

$b=\frac{2x^2(x-5)}{10x}=\frac{2(10)^2(10-5)}{10(10)}=\frac{2(100)(5)}{100}=2(5)=10$

andrew-mc [135]

Answer:

58 students

Step-by-step explanation:

Given

$Total = 85$

$French = 27$

$Geometry = 51$

$History = 38$

$None = 5$

$All = 2$

Required

Students that take only 1 subjects

The attached image illustrates the question.

For French only (x), we have:

$x + 7 -2+10-2+2=27$

$x + 15=27$

Collect like terms

$x =- 15+27$

$x =12$

For Geometry only (y), we have:

$y+10-2+15-2+2=51$

$y+23=51$

Collect like terms

$y=-23+51$

$y=28$

For History only (z), we have:

$z +15-2+7-2+2=38$

$z +20=38$

Collect like terms

$z =-20+38$

$z =18$

Students with one subject is then calculated as:

$1\ subject = x+y+z$

$1\ subject = 12 + 28 + 18$

$1\ subject = 58$
