Nothing is shown.
The triangle is a right triangle, 9, 12 & 15.
The triangle's area = b*h/2 = 9*12/2 = 54 sq meters each end.

------------
The 3 rectangles are 10 by 9, 12 & 15
Area of the 3 = 10*(9 + 12 + 15) = 360 sq meters
-----
Total area = 360 + 2*54
= 468 sq meters

How do I solve 2(x+1) + 5(2x-3)=
Maksim231197 [3]

You multiply 2(x+1) which is 2x+2.

Then you multiply 5(2x-3) which is 10x-15

Finally, you add 2x+2 and 10x-15, and you get 12x-13


The answer is 12x - 13


Hope this helps!

Papa john is 50 years old. His age is 2 years more than 3 times the age of Jimmy John. How old is Jimmy?
mojhsa [17]

Answer:

<h2>Jimmy is 16 old.</h2>

Step-by-step explanation:

J - the age of Jimmy John

50 - the age of Papa John

3J + 2 - the age of Papa John

The euaqtion:

3J + 2 = 50             <em>subtract 2 from both sides</em>

3J + 2 - 2 = 50 - 2

3J = 48          <em>divide both sides by 3</em>

3J/3 = 48/3

J = 16

Quadratic and Ratios...​
lozanna [386]

Answer:

x=0

Step-by-step explanation:

in the quadratic formula to only have one solution

b^{2} -4ac=0 for ax^2+bx+c=0

so we have

ax^2+b=c

ax^2+(b-c)=0

if we insert in the formula we have

0^2-4(a)(b-c)=0\\\\-4ab+4ac=0\\\\4ac=4ab\\\\\frac{4ac}{4a} = \frac{4ab}{4a}\\\\c=b

ax^2+b=c\\\\ax^2=b-b\\\\ax^2=0 since a≠0

\frac{ax^2}{a}=\frac{0}{a}  \\\\x^2=0\\\\x=0
