Answer:

A. Right triangle

Step-by-step explanation:

For problems like this, make use of the Pythagorean Theorem to determine which triangle can be formed.

Thus, there are always 3 sides in a ∆, as we've been given in the question above. The following rule can be use to find out which triangle can be formed:

1. If a² + b² = c², a right triangle is formed.

2. If a² + b² > c², an acute triangle is formed.

3. If a² + b² < c², an obtuse triangle is formed.

Where, c is always the longest side, while a and b are the 2 other shorter side lengths compared to c.

From the question given,

a = 24

b = 45, while

c = 51

Let's find out which of the 3 rules this side lengths fit in, to determine the triangle they form.

24² + 45² ? 51²

576 + 2025 ? 2601

2601 = 2601 (this fits into rule 1 stated above)

Therefore, the side lengths given in the question would form a right triangle.

Three times the quantity five less than x, divided by the product of six and x

Elden [556K]

Answer:

$\frac{3(x-5)}{6x}$

Step-by-step explanation:

we know that

The phrase "Three times the quantity five less than x" means 3 multiplied by the difference of x minus 5

3(x-5)

The phrase "the product of six and x" means the number 6 multiplied by x

therefore

The phrase" Three times the quantity five less than x, divided by the product of six and x" is equal to the quotient of 3(x-5) and 6x

$\frac{3(x-5)}{6x}$

The value of a car depreciates by 35% per year. Work out the current value of a car bought 2 years ago for £20000

Rzqust [24]

First year: the depreciation is (35/100) x 20000 = £7000; now the value of the car is £20000 - £7000 = £13000;

Second year: the depreciation is (35/100) x 13000 = £4550; the current value of the car is £13000 - £4550 = £8450.

Rút gọn (x-4) (x-3) -x(x+5) +82

WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

$\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82$

$=x^2-7x+12-x\left(x+5\right)+82$

$=x^2-7x+12-x^2-5x+82$

$=x^2-x^2-7x-5x+12+82$

$=-7x-5x+12+82$

$=-7x-5x+94$

$=-12x+94$

GIVING BRAINLIEST WHOEVER ANSWER THIS CORRECT THANK U.

Sonja [21]

Answer:

The coordinates of Y' and Z' are, respectively Y'(6,-1) Z'(-2,0)

Step-by-step explanation:

Translations

A given point A(x,y) when translated by the rule (h,k) maps to A'(x+h,y+k).

We are given the point X(3,-2) and its image at X'(2,-4). The rule for the translation used is:

(h,k)=(2,-4)-(3,-2)=(2-3,-4+2)=(-1,-2)

If we apply the same translation to the point Y(7,1) we get the image Y'(7-1,1-2)=Y'(6,-1).

If we apply the same translation to the point Z(-1,2) we get the image Z'(-1-1,2-2)=Z'(-2,0).

The coordinates of Y' and Z' are, respectively Y'(6,-1) Z'(-2,0)

it's a example from another eqaqthion
