Plz do not delete my questions. i will give you 20 points for these two questions. a . and a 5 star rate. but in order for this to happen you have to make sure to show your work and make sure it is right. then i will give you all of that. 1. what is the total surface area of this rectangular pyramid? first picture is for this question. square feet 2. what is the surface area of the square pyramid below? second picture is for this question 96 cm2 122 cm2 132 cm2 144 cm2

Step-by-step explanation:

The total surface area of rectangular pyramid is calculate as;

A = 2x(area of triangle with height 8ft and base 12ft) +2x(area of triangle with height 6ft and base 9.5ft)+ area of rectangle

Hence, the total surface area of the rectangular pyramid is 225 cm²

The area of square pyramid is calculated as:

in second figure we can see base 'b' is 6 and lateral height 'l' is 8.

so,

Put b = 6 and l = 8 in above formula,

Hence, the surface area of the square pyramid is 132 cm²

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
