Hey there! :)
You have to find the area of all of them and add it together.
Formulas:
Area of a square: l · w
Area of a triangle: (b · h) ÷ 2
Square -
l = 3
w = 3
3 × 3 = 9
Triangle -
b = 3
h = 3
(3 × 3) ÷ 2
9 ÷ 2 = 4.5
There are 4 triangles
4.5 × 4 = 18
9 + 18 = 27
The surface area ⇒ 27 cm²
Answer:
32-16=16
16×9=144
Step-by-step explanation:
quantity: the amount of smth
The correct answer is 49!
1/3 32 goes into 96 3 times
Answer:
x= -1.5, y= -1
Step-by-step explanation:
6x= -5+4y
x= (-5+4y) / 6
4((-5+4y) / 6) + 5y = -11
4(-5+4y) + 5*6y = -11*6
-20+16y+30y= -66
16y + 30y = -66+20 = -46
y(16 + 30) = -46
y= -46 / (16 + 30)
y= -46 / 46
y= -1
x= (-5+4(-1)) / 6
x= (-5-4) / 6
x= -9 /6
x= -1.5
