Answer:
Step-by-step explanation:
The volume is [tex] V=l\times w \times h[tex]
So
[tex]V=4x \cdot 5x\cdot (x^2+x+2)\\=20x^2\cdot (x^2+x+2)\\=20x^4+20x^3+40x^2.[/tex]
what is the slope of a line which is perpendicular to the line that has an equation of
21x=7/2y+5
I do not understand this question
First convert the equation in the form of y= mx + c
The equation will be like = y = 6x-5
value of m = 6
The slope of perpendicular line will be = -1/m = -1/6
Consider the following graph to m(x) and determine the following answers in interval notation.
Interval(s) Increasing:
Interval(s) Decreasing:
Positive Interval(s):
Negative Interval(s):
Domain:
Range:
Y-Intercept:
X-Intercept(s):
Relative Minimum(s):
Relative Maximum(s):
Answer: ik relative minimum is -7 and relative maximum is 9

1/8 divided by 11/4 in a fration
Answer:
The answer is 1/22.
Step-by-step explanation:
→ (1/8) ÷ (11/4)
→ (1/8) × (4/11)
→ (1×4)/(8×11)
→ 4/88
→ 1/22 [Simplest form]
Thus, 1/22 is the solution.
1+1/4+1/28+1/70+...+1/x(x+3)=31/24

help me please and thank you
Answer:
the answers are a and c
Step-by-step explanation:
to find the proportions used, you would do 8/3 or 5/a, which are equal, so that gives c.
now, pretend that the second triangle is the original and the second one is the copy (proportionately). then, to find the proportions, you would do 3/8 or a/5, which gives you a.

Answer:
(x+6) (x+8)
Step-by-step explanation:
x² + 14x + 48 = 0
ac = 48
b = 14
(x + 6) (x + 8)

find the distance between the two points rounding to the nearest 10th! PLS HELP ASAP!!!!
Answer:
8.5
Step-by-step explanation:
d = √[(-7+1)²+(-1-5)²]
= √[(-6)²+(-6)²]
=√(36+36)
=√72
= 8.5
Answer:
8.5
Step-by-step explanation:
we can plug those coordinates into the distance formula
d = √(x2 - x1)2 + (y2 - y1)2
d= √((-7)-(-1)^2+((-1)-(5)^2
d = √36+36
d=√72 = 8.48 or 8.5
