Division
Multiplication
Addition
Subtraction

First look at the Brackets
There are no indices in the brackets
There is no division in the brackets
There is a Multiplication in the brackets    7 x 3


For the answer

(9 - 7 x 3 + 4)²
Brackets
Multiplication   7 x 3 = 21
(9 - 21 + 4)²
Addition   -21 + 4 = -17
(9 - 17)² 
Subtraction    9 - 17 = -8
-8² 

Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64

Nataliya [291]

Answer:

2.5 inches

Step-by-step explanation:

1 feet = 12 inches

The length is 16 ft x 12 = 192 inches

The length was scales by an unknown measure which i would represent with x . The equation is as follows

192 inches x a = 4 feet

a = 48

The kitchen was scaled by 48

10 x 12 = 120 inches

120/48 = 2.5 inches

Which expression is eqivalent to 6× + 10×
My name is Ann [436]

16x

Both of these expressions are similar expressions, therefore you can simply add the number in front of the 'x'

6 + 10 = 16

Therefore, 6x + 10x = 16x

Help easy math question!!!
bogdanovich [222]

Answer:

The length of the third side of the triangle is 30.

Step-by-step explanation:

Here is the formula for the Pythagorean Theorem:

a^{2} + b^{2} = c^{2}

The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!

We need to multiply 40 times 40 and 50 times 50.

40 times 40, or 40 squared, equals to 1600.

50 times 50, or 50 squared, equals to 2500.

c^{2} - b^{2}  = a^{2}

Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
