if the length of a rectangle in terms of x is x^2+2x-3 and its width is 2x^2+3x+5, what is the perimeter of this rectangle?
perimeter: ___units
Step-by-step explanation:
perimeter=(L+W)2
L=x^2+2x-3
W=2x^2+3x+5
(x^2+2x-3+2x^2+3x+5)2
(x^2+2x^2+2x+3x-3+5)2
(3x^2+5x+2)2
p=(6x^2+10x+4)units

What shape is produced when slicing a right rectangular pyramid perpendicular to the base?
f(x)= 3x and g(x)= -x+4, so f(g(2))=?
Answer: 6
Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6
Answer:
[tex]f(g(2))=6.[/tex]
Step-by-step explanation:
We have [tex]g(x)=-x+4 \Rightarrow g(2)=-2+4=2[/tex]
Since [tex]f(x)=3x[/tex] then [tex]f(g(2))=f(2)=3.2=6.[/tex]

Answer: x=0
Step-by-step explanation: This is number 9
12=-4(-6x-3)
-4(-6x-3)=12
-4(-6x-3)/-4=12/-4
-6x-3=-3
-6x-3+3=-3+3
-6x/-6=0/-6
x=0
Help me with this!!! Fake answers will get reported
Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right
Can someone help this is due today
Answer:
24
Step-by-step explanation:
[tex] {ba}^{2} = {bc}^{2} - {ac}^{2} \\ {ba}^{2} = {10 }^{2} - {8}^{2} \\ ba = \sqrt{100 - 64} \\ ba = \sqrt{36 } \\ ba = 6[/tex]
Area of triangle = 1/2 × AC × BA
= 1/2 × 8 × 6
= 48/2
= 24 in²
#CMIIWCalculate the breadth if the perimeter is 16cm and the length is 5cm
Step-by-step explanation:
Given,perimeter - 16cm
length - 5cm
find breadth,
perimeter of rectangle = l × b
16cm = 5 × b
b = 16/5
b = 3.2 cm
Step-by-step explanation:
Given
perimeter (P) = 16 cm
Length(L) = 5 cm
breadth (b) = ?
We know
P = 2 (L + b)
16 = 2 ( 5 + b)
16 = 10 + 2b
2b = 16 - 10
2b = 6
b = 6 / 2
b = 3 cm

The Smiths want to fence their square garden, which has an area of 289 square feet. What would be the minimum amount of fencing needed to complete the project? A) 68 feet of fencing B) 17 square feet of fencing C) 289 feet of fencing D) 17 feet of fencing
Answer:
68 feets of fencing
Step-by-step explanation:
Given that:
Area of square garden = 289 ft²
The side length of square garden can be obtained thus :
Area of a square = s²
Where s = side length
s² = 289
s = sqrt(289)
s = 17
Perimeter of square garden : 4s
Perimeter = 4* 17 = 68 feets

since -3×4x=-12x
therefore 2x×1=2x
write the absolute value function as a piecewise function y=6|x-3|
Which equation can be used to find the value of x?
Answer: D
Step-by-step explanation:
The perimeter is all the sides added up
2.5x + 2.5x + 10 + 2 + 10 =>
5x + 22
It is also given that the perimeter is 10.5x
meaning that both these values are equal
5x + 22 = 10.5x

A store sells card games for $6.95 each. Board games sell for $15.00 each. Monica
is buying 3 card games and x number of board games. Which equation can be
used to find y, the total price Monica must pay in dollars?
Answer:
20.85+x=y
Step-by-step explanation:
Since Monica is buying 3 card games, we multiply 3*6.95. Then, we have 20.85. Then, we will add x to 20.85 to find y. So final answer is :
20.85+x=y
