Answer:

let total be U and strawberry be S and.apple be A .

now

n[U]=200

n[S]=56% 0f 200=112

n[A]=44%of 200=88

n[A n S]=30%of 200=60

now

$\bar {A U S}=?$

we have

n[U]=n[A] +n[B]-n[ A n B]+ $\bar{A U S}$

$\bar{A U S}$ =200-112-88+60=60

option C. 60 is a required answer.

Find the value c that will make 9x^2 +30x+c a perfect square trinomial

anzhelika [568]

Answer:

$c = 25$

Step-by-step explanation:

Given :-

A quadratic equation is given to us.
The equation is 9x² + 30x + c .

And we need to find out the value of c for which the given trinomial is a perfect square. On looking at the given expression all the terms are having positive signs before them .So we can rewrite it on the basis of ,

Identity :-

$\implies (a+b)^2=a^2+b^2+2ab$

Let's try to set the equation on this Identity .

The firsr term is 9x² . We can write it as ,

$\implies 9x^2=(3x)^2$

Hence the middle term here should contain 3 and 2 as their factors. Let's Break the middle term .

$\implies 30x = 2.3x.5$

Therefore in order to make the whole expression as perfect square 5² must be replaced by c . The expression would become ,

$\implies 9x^2+30x + 5^2 \\\\\implies (3x)^2+2.3x.5 +5^2\\\\\implies (3x+5)^2$

Hence the value of c should be 25 .

Rick rents a car from a company that charges him $25 per day plus 10 cents per mile driven. Which expression can represent the a

3241004551 [841]

Let x be the number of days and y represent miles driven.

Since it costs 25 per day, you multiply 25 by x.
25x

10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y

25x+.1y

The answer is a.) 25x + 0.1y.
