Answer:
a) 34.64 inches
b) The TV will not fit inside the TV cabinet
Step-by-step explanation:
Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )
a)If it is 20 inches tall, how wide is the screen ?
We solve using the formula:
Diagonal ² = Width² + Height²
Diagonal = 40 inches
Height = 20 inches
40² = Width² + 20²
Width² = 40² - 20²
Width = √40² - 20²
Width = √(1200)
Width = 34.641016151 inches
Approximately = 34.64 inches
b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?
From the above calculation, the width of the TV = 34.64 inches
Hence the width of the cabinet has to be equal to or more than 34.64 inches
Hence, The TV will not fit inside the TV cabinet
Answer:
x = -3
y = 6
Step-by-step explanation:
3x + y = -3
x = -y + 3
3x + y = -3
3(-y + 3) + y = -3
-3y + 9 + y = -3
-3y + y + 9 = -3
-2y + 9 = -3
-2y = -3 - 9
-2y = -12
y = -12/-2
<u>y = 6</u>
x = -y + 3
x = -6 + 3
<u>x = -3</u>
Step-by-step explanation:

Now, let's look for common factors. The first one is
After we take that out, we are left with 14 and 22. We can take a 2 out of both of these, so the greatest common factors is
