Answer:
4√34
Step-by-step explanation:
Let the unknown side be y
y^2 = 20^2 + 12^2
y^2 = 400 + 144
y^2 = 544
Take the square root of both side
y = √544
y = √(16x34)
y = √16 x √34
y = 4√34
Answer:
C
Step-by-step explanation:
You have to divide both sides by the coefficient of x
Answer: x = -1
Step-by-step explanation:
Starting:
x-5(x+1)=3x+2
Simplify the left side:
-4x-5=3x+2
Move all the terms with an x to the left:
-7x-5=2
Move all the terms without an x to the right:
-7x=7
Divide both sides by -7:
x = -1
Answer:
4/8 - 2/8 = 2/8 = 1/4
Step-by-step explanation:
To find the area of the larger figure, let's multiply the length by the width.
9 ft * 4 ft = 36ft^2
Let's do the same thing with the smaller figure.
3 ft * 4 ft = 12ft^2
Let's add the area of both figures together.
36ft^2 + 12ft^2 = 48ft^2
