Let the length be l
Then,
l *(l-3)= 88
l²-3l =88
l²-3l-88=0
l²-11l +8l -88 =0
l(l-11) + 8(l-11) =0
(l+8)(l-11)=0
As, l can't be negative, length=11cm and width=(l-3)=11-3 =8 cm
Answer: distance from 15.3 to zero on a number line
Step-by-step explanation:
3x³+6x²+9x+10
or
6x³+9x²+3x+5

.
the constant can be any number.
square root is 74.986
round that to the tenth and get 74.99
74.99^3=421706.2725
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)
m = = = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using B(2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
