To calculate the area of a rectangle you multiply the length of the the sides, on 38) the sides are 4 and (3x-2) so to find the area do 4 x (3x-2) = 12x-8
To find the area of a right angled triangle you multiply the two sides and then divide by two, so for 39) and 40) follow this method but divide by two after as they’re triangles to find the area for these
Answer:
p=25
Step-by-step explanation:
5p-4(p+3)=13
5p-4p-12=13
x-12=13
x=13+12
x=25
a check:
5(25)-4(25+3)=13
125-100-12=13
125-112=13
13=13
Answer: c) 3.2 inches
<u>Step-by-step explanation:</u>
Let x represent the width of the frame
Then the area of the frame is:
(x + 12)(x + 14) = 261.44
Rewrite it in Standard form of a quadratic equation:
x² + 26x + 168 = 261.44
x² + 26x - 93.44 = 0
Use Quadratic Formula to solve for x:

Answer: The second step for copying a line segment is to set the compass to the length of the line segment to be copied.
When copying a line segment, you must first create your starting point.
Then, you need to set your compass to the length of the line segment to be copied.
Finally, you can make an arc and finish your line segment.
5/8 or .625 is the answer
