Answer:
x=-2.5
Step-by-step explanation:
2x-10÷4=3x
2x-2.5=3x
-2.5=x
Formula for the area of the triangle:
1/2 bh
b = base
h = height
#6.
Area = 36 in²
Base = 18 in
36 = 1/2(18)h
36 = 9h
36 ÷ 9 = h
4 = h
height = 4 in
#7.
Area = 2 ft²
Height = 1 ft
2 = 1/2 b (1)
2 = 1/2 b
2 ÷ 1/2 = b
4 = b
Base = 4 ft
#8.
Area = 42 in²
Base = 12 in
42 = 1/2 (12) h
42 = 6h
42 ÷ 6 = h
7 = h
Height = 7 in
Notice that the answers have no exponents (²). That is because they are used only on the area of shapes as units.
Since you find the area by multiplying things together, for example x · x = x², the exponent is there.
You do not need to worry about this being in the calculation. This will just be in units such as:
cm²
ft²
in²
m²
Just remember to use these exponents in the units for the areas.
As mentioned before, banks<span> basically make money by lending money at rates higher than the cost of the money they lend. More specifically, </span>banks<span> collect interest on loans and interest payments from the debt securities they own, and pay interest on </span>deposits<span>, CDs, and short-term borrowings.</span>
Answer:
12
Step-by-step explanation:
3 x 4
3 is how far the shape goes to the left.
4 is how far it goes to the bottom
you multiply the two numbers to cover the area
