Answer:
x = -4
y = -21
Step-by-step explanation:
To solve this, we will need to set up a system of equations and get rid of a variable.
-3x - 2y = 54
-6x + 2y = -18
From this, we can see that the 'y' variables can be cancelled out if we add the two together. This means that we must add these equations to each other to cancel out the 'y' variables:
-3x - 2y = 54
-6x + 2y = -18
-------------------- +
-9x = 36
x = -4
Since we have solved for 'x', we can simply plug this value into an equation to find 'y'.
-3(-4) -2y = 54
12 - 2y = 54
-2y = 42
y = -21.
Answer:
800 in²
Step-by-step explanation:
Applying,
TSA (A) = Area of the base+ Lateral area of the
A = lw+1/2ps................ Equation 1
Where l = lenght of the base, w = width of the base, p = perimeter of the base, s = slight height of the base.
But,
p = 2(l+w)............. Equation 2
Substitute equation 2 into equation 1
A = lw+1/2[2(l+w)s)
A = lw+s(l+w)............. Equation 3
From the question,
Given: l = 16 in, w = 16 in, s = 17 in
Substitute these values into equation 3
A = (16×16)+17(16+16)
A = 256+544
A = 800 in²
16=4 because in order to get 4 you need have to divide 16 into 4
