Answer:
38.5
Step-by-step explanation:
1.)use BEDMAS rule so multiply first
10 × 2.5 + 13.5
=25 + 13.5
2.) then add
= 25 + 13.5
= 38.5
-1 is the first answer and for #2 is the 4th answer.

Answer:
Perimeter = 42 cm.
Step-by-step explanation:
The 2 legs are equal in length as it is an isosceles trapezoid.
Area of trapezoid = (h/2)(a + b) where a and b are the parallel bases.
So
(5/2) (a + b) = 45
a + b = 45 * 2/5 = 18 cm.
We are given that the length of a leg (L) is 2/3 * sum of the bases, so:
L = 2/3(a + b)
= 2/3 * 18
= 12 cm.
The perimeter = a + b + 2L
= 18 * 2*12
= 42 cm.
Answer:
y=-5x+4
Step-by-step explanation:
Slope intercept form is y=mx+b so you just plug m and b in :)
