side of the triangle = 12 inches
side of the square = 8 inches
12 is 4 more than 8
perimeter of the square = 4(8) =32 inches
perimeter of the triangle = 3(12) = 36 inches
36 is 4 more than 32
Let T= side of the triangle and S = side of the square
3T = 4S+4
T=S+4
3(S+4) = 4S+4
3S+12 = 4S +4
4S-3S = S = 12-4 = 8
T =8+4 = 12
A and c are the correct answers
Answer:
-13 + 9
Step-by-step explanation:
if you have -13° and then it rises 9°, it will be added since it’s rising and rise can be a way of addition. so -13 + 9 is your answer
<2 = 45 degrees They are corresponding angles
74 + <1 + <2 = 180 it makes a straight line
74 +<1 +45 = 180
119 +<1 =180
subtract 119
<1 = 180 -119
<1 = 61 degrees
1. To find out if (0,3) is a solution to y = x +3 you replace x and y with (0,3)
y = x + 3
3 = 0 + 3
3 = 3 Correct
The answer is YES
2. To find out if (1,-4) is a solution to y = -2x you replace x and y with (1,-4)
y = -2x
-4 = -2(1)
-4 = -2 Incorrect
The answer is NO
