Answer:
1/2 - 3(1/2 + 1)²
simplify the expression (1/2 + 1)
1/2 - 3•(3/2)²
using PEMDAS, we see we have to evaluate the exponent first
(3/2)² = 9/4
rewrite the equation
1/2 - 3 • (9/4)
multiply 3 by (9/4)
1/2 - (27/4)
subtract
-25/4
(1 + 1/3)² - 2/9
simplify the expression (1 + 1/3)
(4/3)² - 2/9
using PEMDAS, we see we have to evaluate the exponent first
(4/3)² = 16/9
rewrite the equation
(16/9) - (2/9)
subtract
14/9
Answer:
x = 25
Step-by-step explanation:
<em>Step 1: Identify the similar triangles</em>
Triangle DQC and triangle DBR are similar
<em>Step 2: Identify the parallel lines</em>
QC is parallel to BR
<em>Step 3: Find x</em>
DQ/QB = DC/CR
40/24 = x/15
x = 25
!!
Since y=-3 you need to set up the equation
-20-(-3)
And all you have to do is simplify
So your answer will be
-17
Hope this helped :)
Have a great day
Answer:
Step-by-step explanation:
Hi!
Since an equilateral triangle means that every side is equal, our triangle will have 12 on all sides.
To find the height of an equilateral triangle we use 
.
.
So the height is 
.
Now we have to solve 12 * ÷ 2.
.
Thus, the area of the triangle is 
.
Hope this helps!
