Answer:
95 square inches
Step-by-step explanation:
Start by finding the surface area of the four triangles. 7x5=35 35÷2=17.5. 17.5x4=70. Then take the surface area of the square, 25, and add it to the surface area of the triangle. 70+25=95.
Hope this helps!
Answer:
(2, - 1 )
Step-by-step explanation:
3x - y = 7 → (1)
2x + 3y -= 1 → (2)
multiplying ( 1) by 3 and adding to (2) will eliminate y
9x - 3y = 21 → (30
add (2) and (3) to eliminate y
11x = 22 (divide both sides by 2 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
2(2) + 3y = 1
4 + 3y = 1 (subtract 4 from both sides )
3y = - 3 ( divide both sides by 3 )
y = - 1
solution = (2, - 1 )
