Find the surface area of the square pyramid.
a. 154 m2
b. 308 m2
c. 203 m2
d. 357 m2

355

Step-by-step explanation:

since it is square all the sides edges on the base are equal. the base time height of a triangle is to be divided by 2.

this is the equation:

(7x7) + (11x7)4

49+[77(4)]/2

49 + 308/2

49 + 154

203

1. perpendicular

2. parallel

3. perpendicular

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
