Answer:

126 square feet

Step-by-step explanation:

The formula for the area of a triangle is ...

A = (1/2)bh . . . . . where b is the base length and h is the height

Here, you have a triangular face that has a base of 6 ft and a height of 14 ft. Its area is ...

A = (1/2)(6 ft)(14 ft) = 42 ft^2

The lateral area of the pyramid consists of 3 such triangles, so the lateral area is ...

LA = 3·(42 ft^2) = 126 ft^2

Answer:

$-x^{2}+4x$

Step-by-step explanation:

we have

$(x^{2}+x)-(2x^{2} -3x)$

step 1

Eliminate the parenthesis

$x^{2}+x-2x^{2} +3x$

The symbol of the term 3x is incorrect, must be positive instead of negative

$-(-3x)=+3x$

Group terms that contain the same variable

$(x^{2}-2x^{2})+(x+3x)$

Combine like terms

$-x^{2}+4x$
