Plz help find the area asap i really need help with the math problems
lozanna [386]

Answer:

uh the area is 45 for the first one because 15*9 is 135 and 15*6 is 90 because you get 6 from 15-9 to get the length for the triangle. Then 135-90 is 45.

Step-by-step explanation:

The area for the second shape is 114 because you will take 14 multiplied by 12 and you get 168, then you will take 6*9 which is 54 and subtract that from 168, and you should get 114.

The area for the third shape is i dont even know because it doesnt give numbers unless your trying to find it with the letters but at least you got the first two

A. She can multiply the bottom equation by -4 and then add the equations to solve for h.

-4g - 15h = -17

4g - 20h = -52

Add them to get

-15h = -17

-20h = -52

Ethan is thinking of a negative number that is lower than -4 and higher than
s2008m [1.1K]

When the number is odd and a multiple of 3, the number that Ethan is thinking of is -9.

<h3>How to illustrate the number?</h3>

In mathematics, a multiple is the product of any quantity and an integer. It should be noted that, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

In this case, Ethan is thinking of a negative number that is lower than -4 and higher than -10 and his number is odd and a multiple of 3. The number is -9 since 9 is a multiple of 3.

kramer

Answer:

V=144\ cm^3

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm

#The volume of the beam can then be calculated as:

V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3

Hence, the beam's volume is 144\ cm^3
