What is the perimeter of the larger triangles
Solve:4 to the 6th power times 4 to the fourth power
Answer:
4¹⁰
Step-by-step explanation:
You don do the figuring out want number is in each exponent you simply add because you have the same base and if its multiplication you actually do addition in which multiplication is repeated addition. same for division but subtraction instead because you are lowing the number :)
Pls, help me! I have less than 5 minutes to complete this. This is worth 1/2 of my grade.
Answer:
A= 16 cubes²
Step-by-step explanation:
The length, or the base, is 4 units. The height of the shape is 2, and the width is 2. If we use the formula of volume, l·w·h, we can say that V=4x2x2. So, 4x2x2=16.
1. What domain restrictions apply to this rational expression? show work
x2 +10x+9/
x2-9
9514 1404 393
Answer:
x ≠ -3, x ≠ 3
Step-by-step explanation:
As with any rational function, the denominator cannot be zero. Here that means we cannot have x such that ...
x² -9 = 0
(x -3)(x +3) = 0
x = 3 or -3 . . . . . . . values not allowed in the domain
Compare -3 and 9. Which of the following is true?
Jennifer deposits $1,000 into an account that is compounded monthly for 4 years. The account earns 7% interest. What is the ending balance in the account at the end of the 4 years (assuming no new deposits or withdrawals)? SHOW THE WORK PLEASE
9514 1404 393
Answer:
$1,322.05
Step-by-step explanation:
The compound interest formula is appropriate.
A = P(1 +r/n)^(nt) . . . principal P earning annual rate r for t years, compounded n times per year
You have P=1000, r=.07, n=12, t=4, so the balance is ...
A = $1000(1+.07/12)^(12·4) ≈ $1000(1.322054)
A = $1,322.05
Jennifer's ending balance is $1,322.05.

Answer:
Description
Step-by-step explanation:
1. Factor 2x^2+11x+12 -> (2x+3)(x+4)
x=-4, -3/2
Both numbers are rational numbers as both can be expressed in the form in a quotient with integer values.
2. If discriminant is negative, then solutions are imaginary, meaning that the discriminant is less than 0, so you can set up this equation.
11^2 - 4(a)(12) < 0
121 - 48a < 0
a>121/48
The closest integer to 121/48 (~2.52) such that it satisfies the above conditions is 3, so the lowest value for a is 3.

Macy’s is having a one-day 35% off special. If Sarah bought an item for $124, how much was the discount?
Answer: Mark me Brainliest :)
$80.92
Step-by-step explanation:
Given:
discount : 35%
Original cost : $124.50
Discount:
$124.50 x 35% = 43.575 ⇒ $43.58
Discounted price
$124.50 - 43.58 = $80.92
Answer:
$80.93
Step-by-step explanation:
If the black square rotates at a rate of 2 inches per second, how long would it take for one full rotation?
Answer:
The answer is below
Step-by-step explanation:
The question is not complete.
Let us assume that the black square rotates in a circular part of radius 1 inch.
Therefore, in one full rotation the distance covered (θ) is the same as the perimeter of the circular part. Therefore:
θ = 2πr = 2π(1) = 6.28 inch
The time taken to complete one full rotation (t) is:
t = θ / v
t = 6.28 / 2
t = 3.14 seconds

I need help please
Answer:
distance = 10.6
Step-by-step explanation:
A's coords are (5, 6)
D's coords are (-2, -2)
So the total horizontal distance between A and D is:
5 + 2 = 7
...and the total vertical distance is:
6 + 2 = 8
Now use Pythagorean Theorem:
7^2 + 8^2 = distance^2
distance^2 = 49 + 64 = 113
distance = squareroot of 113
distance = 10.6

What is 2x+5=25? I would like to know it step by step please.
Step-by-step explanation:
subtract 5 from 25 and it should look like this
2x=20
divide 2 and your is 10
Answer:
No problem! Well first off, x is 10.
Step-by-step explanation:
So you know that 2 times a certain number, plus 5, is 25. The first step to solving this problem is subtracting 5 from the total (25) to give you 20. This just makes it easier to find x, so you technically don't have to do it. So now, you know that 2 times a certain number equals 20 (because we got rid of the 5). Now, just divide your number (20) by 2, to get that x is 10. Let's check our answer.
2(10) + 5= 2520 + 5= 25
25= 25.
Works out!

Need help ASAP ASAP
Answer:
X = 70, y = 21
Step-by-step explanation:
53 + 6y + 1 = 6y + 54
6y + 54 = 180
180 - 54 = 126
6y = 126
126 ÷ 6 = 21
Y = 21
21 × 6 + 1 = 127
127 = 2x - 13
127 + 13 = 140
140 ÷ 2 = 70
X = 70

If 3x + 2 = 4, what is the value of 6x - 4?
2
8
0
-2
Answer:
0
Step-by-step explanation:
3x + 2 = 4
4-2 = 3x
2 = 3x
x = 2/3
2/3 x 6 = 12/3 = 4 - 4 = 0

What is the answer to this equation?
-3y > -14
Answer:
y < 14/3
Step-by-step explanation:
You can immediately negate the negative from both sides by canceling the -1.
Divide both sides by 3, when you divide a < or > by anything you have to switch the sign it faces. So in this case
-3y > -14
=> 3y < 14
y < 14/3

Answer:
Step-by-step explanation:
Perimeter of the deck = (d + 5) + (d + 5) + (d + 5) + (d + 5)
1). By grouping method,
Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)
2). Perimeter = Number of sides × Length of a side
= 4(d + 5)
3). Expression from problem 1,
Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)
= 4d + 20
= 4(d + 5)
Expression from problem 2,
Perimeter = 4(d + 5)
Bot the expressions are same.
