1/2 plus 1/3 is 5/6.
You have to find the common denominator
Sum of angles in a triangle = 180
180-90-26
=64
Answer:
its the last one.
Step-by-step explanation:
easy way to do inverse functions:
write out equation :
y = 2
+ 2
Switch the x and y:
x = 2
+ 2
Solve for y :
x = 2 + 2
subtract 2 both sides
x - 2 = 2
Divide both sides by 2
- 
=
reduce fraction and square root both sides
Answer:
4x^2 +84x+440
840 in^2
Step-by-step explanation:
The length of the picture and frame is x+ 22+x= 2x+22
The width of the picture and frame is x +20+x = 2x+20
Area is length times width
A = (2x+22) *(2x+20)
We can FOIL to find the area
first 2x*2x = 4x^2
outer 2x*20 =40x
inner 2x*22 = 44x
last = 22*20 = 440
Add these together
4x^2 +40x+44x+440
4x^2 +84x+440
b. x=4
4x^2 +84x+440
4(4)^2 +84(4) +440
4*16 +336+440
64+776
840
Let w be the width then w+4 is the length and 2*w+2*(w+4)=4*w+8 is the expression for the perimeter. So
4*w+8>=48
4*w>=40
w>=10
