I think it's A. I can't really see the graphs clearly. It's the one that crosses at (15,2)
Answer: 410 square km
Step-by-step explanation:
The area of each of the triangles with their base on the 10 km side is
, so their combined area is
.
The area of each of the triangles with their base on the 12 km side is
, so their combined area is
.
The area of the bottom rectangular face is
.
So, the total surface area is

Answer:
25
Step-by-step explanation:
Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;
<1 + <2= 180
123+2x+7 = 180
130+2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
Hence the value of x is 25
Answer:
y=7x + 5
Step-by-step explanation:
sub into y= mx + c
where m = slope/gradient (7)
and c = y-value of y-intercept (5)
