Answer:I'm guessing 9×6? 54?
Step-by-step explanation:
4374. You can draw 54 lines horizontally and 81 vertically, and count the intersections of the lines. Is this what your talking about? Not very efficient, I might add.
Perimeter of the frame is 60 in and perimeter of the picture is 52 in. Area of the picture is 160 in²
Step-by-step explanation:
- Step 1: Find the perimeter of the frame when width = 12 in and length = 18 in
Perimeter of the frame = 2 (length + width)
= 2(18 + 12) = 2 × 30 = 60 in
- Step 2: Find the perimeter of the picture inside the frame.
Length of the picture = 18 - 2 = 16 in
Width of the picture = 12 - 2 = 10 in
⇒ Perimeter of the picture = 2 (length + width)
= 2 ( 16 + 10) = 2 × 26 = 52 in
- Step 3: Find the area of the picture.
Area = length × width
= 16 × 10 = 160 in²
Answer:
f(x)=24
Step-by-step explanation:
Replace x in the function with the value 4.
f(4)= (4)^2 + 3(4) - 4
16 + 12 -4
28 - 4
F(x)= 24
The number that was left out is 70.
<h3>What is the number that was left out?</h3>
Average is the sum of a set of numbers divided by the total numbers in the data set.
Average = sum of numbers / total numbers
- Sum of numbers when there are 8 numbers = 56 x 8 = 448
- Sum of numbers when there are 7 numbers = 54 x 7 = 378
- Difference = 448 - 378 = 70
