There are four triangles and one square, the areas of which can be added together to form the total surface area.
Area of triangle = 0.5bh
= 0.5*16*15
= 120 cm^2
Since there are four triangles, the total area for them would be 120*4 = 480 cm^2
Area of square = 16^2 = 256
Total surface area = 256 + 480 = 736 cm^2
<span>Earths crust mineral composition are silicon oxide (SiO2),Magnesium monoxide (MgO),Ferrous oxide(FeO),Calcium monoxide (CaO),Sodium dioxide(Na2O) ,Potassium dioxide(K2O), while the Earths crust are sodium,magnesium,potassium,calcium,iron,aluminum,silicon,and oxygen .Because Earth is based on chemical composition and split up into a crust,mantle,outer core and inner core.</span>

Answer:
(c) For p = 15,
leaves a remainder of -2 when divided by (x-3).
Step-by-step explanation:
Here, The dividend expression is
= E(x)
The Divisor = (x-3)
Remainder = -2
Now, by <u>REMAINDER THEOREM</u>:
Dividend = (Divisor x Quotient) + Remainder
If ( x -3 ) divides the given polynomial with a remainder -2.
⇒ x = 3 is a solution of given polynomial E(x) - (-2) =
= S(x)
Now, S(3) = 0
⇒![4x^2-p(x)+9 = 4(3)^2 - p(3) + 9 = 0\\\implies 36 - 3p + 9 = 0\\\implies 45= 3p , \\or p =15](https://tex.z-dn.net/?f=4x%5E2-p%28x%29%2B9%20%3D%204%283%29%5E2%20-%20p%283%29%20%2B%209%20%3D%200%5C%5C%5Cimplies%2036%20-%203p%20%2B%209%20%3D%200%5C%5C%5Cimplies%2045%3D%203p%20%2C%20%5C%5Cor%20p%20%20%3D15)
or, p =1 5
Hence, for p = 15,
leaves a remainder of -2 when divided by (x-3).
