Answer:
x<-1
Step-by-step explanation:
2(x+6)<10
Distribute 2x+12<10
Subtract 12 2x<-2
Divide 2 x<-1
Area=legnth times width
a=lw
area=432
width is 3/4 its lenth
w=3/4 times l
subsitute
a=l(3/4 times l)
a=432
432=l(3/4 times l)
432=3/4l^2
multiply both sides by 4/3 to clear fraction
1728/3=l^2
576=l^2
take the squaer root of both sides
24=l
subsitute
w=3/4l
w=3/4(24)
w=18
legnth=24 feet
width=18 feet
Answer:
A =200.96 ft^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
The radius is 8
A = pi 8^2
A = 64 pi
Letting pi = 3.14
A = 64 ( 3.14)
A =200.96 ft^2
A quadratic equation has the general form
of: <span>
y=ax² + bx + c
It can be converted to the vertex form in order
to determine the vertex of the parabola. It has the standard form of:
y = a(x+h)² - k
This can be done by completing a square. The steps are as follows:
</span><span>y = 3x2 + 9x – 18
</span>y = 3(x2 <span>+ 3x) – 18
</span>y + 27/4= 3(x2 <span>+ 3x+ 9/4) – 18
</span>y = 3(x2 + 3/2)^2 – 99<span>/4
</span>
Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.
Answer:
D. x + 4y + 7
Step-by-step explanation:
A constant term is a term that is a number with no variables (letters) attached to it.
In this case, D is your answer, for the term 7 is a constant, with no variables next to it.
