The area of the parallelogram is mathematically given as
A = 7 square units Option B
<h3>What is the area of the parallelogram?</h3>
Generally, the equation for a parallelogram is mathematically given as
A=bH
Where
b=4.123
and
H=1.75
Hence
A=3*1.75
A=7.2square units
In conclusion, a parallelogram
A = 7 square units

B
rearrange into standard form : ax² + bx + c = 0 (a≠ 0)
2x² - 3x - 2 = 0
(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )
x - 2 = 0 ⇒ x = 2
2x + 1 = 0 ⇒ x = - 0.5
Answer:
(5,2) (-2,5) this is how you solve an equation using simple graphd
0.8 inches
the volume (V) of a sphere is calculated using the formula
V = πr³
change the subject and express in terms of r
multiply both sides by 3
3V = 4πr³ ( divide both sides by 4π )
r³ = 3V / 4π ( take the cube root of both sides )
r = ∛( 3V /4π )
sphere A with V= 40
r = ∛ (120 / 12.56 ) = 2.122
sphere B with V = 10
r = ∛(30 / 12.56 ) = 1.337
sphere A - sphere B = 2.122 - 1.337 = 0.8 inches ( to nearest tenth )
