Have you used PEMDAS if not the abbreviation stands for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. So you start with 3² = 3x3 = 9 now 5x6=30 so now you have a equation of (4 + 7 x 9 - 30) = 4 + 63 - 30 = 67 - 30 = 37 I hope I helped!!!!

small rectangular top area = 6x5 = 30 cm^2

total top area = 308 + 30 = 338 cm^2

volume = 338 x 20 = 6760 cm^3

I need some serious help with standard form, Im really confused . Here's a problem ,

OLEGan [10]

I can see that the equation given above is a linear equation since y and x are the only variable and the degree is one. The standard form of a linear equation is written as:

Ax + By = C

We write the given equation into standard form as follows:

y - 2 = 2(x - 3)
y - 2 = 2x - 6
y -2x = -6 +2
y - 2x = -4
2x - y = 4

coldgirl [10]

Answer:

The least common denominator of the fractions is 24

Step-by-step explanation:

we know that

The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions

we have

7/8

Multiples of 8 -------> 8,16,24,32,...

5/6

Multiples of 6 -------> 6,12,18,24,...

24 is a common multiple of 6 and 8. It is their lowest common multiple

Alternative Method

we have

$8=2^{3}$

$6=2*3$

The least common multiple are those common and non-common numbers with the greatest exponent

$lcm= 2^{3}*3=24$
