Answer:
7 7/4 t - 1
Step-by-step explanation:
The perimeter of the quadrilateral is the sum of all the sides combined together
Given the length of the sides as (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2),
Taking the sum;
Perimeter = (2 1/4t−5)+(4t+3)+(1/2t−1)+(3t+2)
Perimeter = 9/4 t - 5 + 4t + 3 + 1/2 t - 1 + 3t + 2
Collect like terms;
Perimeter = 9/4 t + 1/2 t + 4t + 3t -5 + 3-1 + 2
Perimeter = (9t-2t)/4 + 7t -1
Perimeter = 7/4 t + 7t - 1
Perimeter = 7 7/4 t - 1
Answer:
y = 4/3x-7/3
Step-by-step explanation:
Slope intercept form is y=Mx+b; m=slope & b= y intercept
y=-4/3x+b
Now substitute x & y with the point given
(-9)=-4/3(5)+b
-9= -20/3+b
+20/3 +20/3
-7/3=b
Now substitute this into the original equation
y = 4/3x-7/3
Answer:
90
Step-by-step explanation:
18:
18*1=18
18*2=36
18*3=54
18*4=72
18*5=90
18*6=108
45:
45*1=45
45*2=90
45*3=135
Therefore, 90 is the correct answer
A+b+c=180
subsittute
x+25+x-5+c=180
2x+20+c=180
minus 20 both sides
2x+c=160
mius 2x
c=160-2x
