Answer:

-12x + 94

Step-by-step explanation:

Simplify:

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

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

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

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

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

$=-7x-5x+94$

$=-12x+94$

For what value of x is line m parallel to line n? Enter your answer in the box. x = ?

Zielflug [23.3K]

Answer-

The value of x is 10

Solution-

When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.

When the line are parallel the corresponding angles are equal in measurement.

As m and n are parallel line, so

$\Rightarrow 8x+50=130$

$\Rightarrow 8x=130-50$

$\Rightarrow 8x=80$

$\Rightarrow x=10$

Compute using significant digits. What is the area of a parallelogram with length 17.25 mm and width 5.065 mm?

Dmitriy789 [7]

Answer: Option 'a' is correct

Step-by-step explanation:

Since we have given that

Length of parallelogram =17.25 mm

Width of parallelogram =5.065 mm

As we know the formula for " Area of parallelogram"

Area of parallelogram is given by

$Area= length \times breadth\\\\17.25\times 5.065=87.03 \ mm^2$

Hence, option 'a' is correct .
