Write an expression for the area of a triangle with a height of 2x^2 units and a base of 5x^2+4x units
Stolb23 [73]

Answer:

The area of the triangle is 5x^4 + 4x^3 square units

Step-by-step explanation:

Given

Shape: Triangle

Height = 2x^2

Base = 5x^2+4x

Required

The area of the triangle

The area of a triangle is calculated as thus;

Area = \frac{1}{2}(base)(height)

By substituting Height = 2x^2 and Base = 5x^2+4x; This gives

Area = \frac{1}{2}(5x^2 + 4x)(2x^2)

Area = \frac{(5x^2 + 4x)(2x^2)}{2}

Area = (5x^2 + 4x)(x^2)

Open Bracket

Area = 5x^2 * x^2 + 4x * x^2

Area = 5x^4 + 4x^3

Hence, the area of the triangle is 5x^4 + 4x^3 square units

Line L passes through the point (-1, 1) and is PARALLEL to the line shown here. An equation of line L is
Pachacha [2.7K]
The problem cannot be fully solved because you did provide the line on which the line is parallel/ but i can give you the steps on how to solve it. first solve the slope of the parallel line by
m = ( y2 - y1 ) / ( x2 - x1 )
then the slope of that line is equal to slope of line passing pooint ( -1 , 1)
then solve the y intercept of the line using
y = mx + b
where b is the y intercept
then you will have the equation of the line
