Answer:
so basically
the area of the square; (5cm)^2 = 25cm^5
the area of the triangle; (4cm.5cm)/2 = 10cm^2
which means that r = √25cm^2/10cm^2 = √25/10 cm^2 or √10/25 cm^2
english is not my first language so i do not know what combined means but if u explain a little more i will try to help u
-> ok edit edit;
1cm/5in. = r
5cm => 25in.
z^2= area of a square so
25in.25in= 625 in^2
4cm => 20in.
5cm => 25in.
h.b/2 = area of a triangle so
20in.25in./2 = 250in.^2
250in.^2 + 625in.^2 = 875in.^2
so answer B
Answer:
-24
Step-by-step explanation:
-1(3^2)+(-15)
-9+(-15)
-24
Front end estimation for this question would be to the nearest hundred. So 125 rounded to the nearest hundred is 100, 123 to the nearest hundred is 100, 392 to the nearest hundred is 400, and 294 to the nearest hundred is 300. Adding 100 + 100 + 400 + 300 would be 900.

Answer:
x=1
y=0
Step-by-step explanation:
x+3y = 1 equation 1
-5x+4y = -5 equation 2
using equation 1 we have:
x+3y = 1
x= 1-3y equation 3
using equation 3 in equation 2 we have:
-5(1-3y) +4y = -5
-5 + 15y +4y = -5
19y -5 = -5
19y = -5 +5
19y = 0
y=0
so we have:
x= 1-3y
x= 1- 3(0)
x=1
