Answer:752+136=888

Step-by-step explanation:

Answer:

752+136=888

Step-by-step explanation:

Using the tip, (4+5=9 is equal to 5+4=9), just switch the two numbers that add up to 888. So instead of 136+752=888, do 752+136=888 because both of those add up to the same number.

Solve the following equation.
U + 2 = 4

Answers

Answer:

U=2

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.

U +2= 4
-2 -2
U = 2
2 + 2= 4

(2, 1) and (x, 5). There are 2 possible values for x. Find these values.

The smaller value of x = ?

The larger value of x = ?

Answers

Answer:

d = √(x_2 - x_1)² + (y_2-y_1)²

5 = √(x - 2)² + (5-2)²

x = -3 or x =6

Step-by-step explanation:

d = √(x_2 - x_1)² + (y_2-y_1)²) - that is the distance formula

d = 5

x_2 = x

x_1 = 2

y_2 = 5

y_1 = 1

5 = √(x - 2)² + (5-2)²

x = -3 or x =6

find surface area of the square pyramid!!! pls i need help with explaining!!!!!

Answers

Answer:

39 square yards

Step-by-step explanation:

The base is a square, so the area is 3 x 3 = 9.

Each side is a triangle, and the formula for that is (1/2)(base)(height)

The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30

Add the base and sides

30 + 9 = 39

Answer:

39 yards

Step-by-step explanation:

surface area = A + [tex]\frac{1}{2}[/tex] ps

A = area of the base

p = perimeter of the base

s = slant height

the base of the pyramid is a square, all sides and angles are equal

; 3 yards

; area of a square = l x w

; area of the base = 9 yd (A)

perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)

slant height = 5 yd (s)

; sub it into the formula

surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5

surface area = 39 yd
