Answer:
Surface area of square pyramid shown in picture:
A = area of 4 triangles + area of square
= 4 x 4 x 3 x (1/2) + 3 x 3
= 33 (ft)
=> Option 4 (last one) is correct
Hope this helps!

Answer:
4x + 7
Step-by-step explanation:
7x+4-3x+3
First put the like terms together
7x+4-3x+3 = (7x - 3x) + (4 + 3)
= 4x + 7
That's the associative property of addition
it is normally written as
(a+b)+c=a+(b+c)
which is like what you have
(17+4)+9=17+(4+9)
Apples : 5 3/4 * 2 1/2 = 23/4 * 5/2 = 115/8 = 14 3/8 lbs
flour : 6 3/4 * 2 1/2 = 27/4 * 5/2 = 135/8 = 16 7/8 cups
margarine : 1/8 * 2 1/2 = 1/8 * 5/2 = 5/16 cups
sugar : 3 5/8 * 2 1/2 = 29/8 * 5/2 = 145/16 = 9 1/16 cups
cinnamon : 2 * 2 1/2 = 2/1 * 5/2 = 10/2 = 5 teaspoons
<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a²x(-3b²)x2c. Note that 5, -3 and 2 are
coefficients and a², b² and c are variables. Multiply first the coefficients 5, -3
and 2 and you get -30. Always remember that in multiplying numbers, especially
variables, the base of the exponent must be equal. However, you have variables
of a²,
b²
and, c. You cannot multiply or add them because they are different. So the
answer is -30a² b²c.</span>
