The longest side of a triangle is twice as long and the shortest side and the remaining side is 25 cm if the perimeter is 70 cm find the length of the three sides of the triangle.
Answer:
30 cm
25 cm
15 cm
Step-by-step explanation:
x = longest side
y = shortest side
x + y + 25 = 70
x = 2y
using the second equation as substitute in the first equation we get
2y + y + 25 = 70
3y = 45
y = 15 cm
x = 2y = 2×15 = 30 cm
(4xz)³-2xy
x= 2 y=(-4) z= 1

What is a good estimate for the solution to the equation x = 95? How did you come up with your estimate?
Answer:
Answer: My estimation is 5
Step-by-step explanation:
[tex] {x}^{3} = 95[/tex]
Introduce power of ⅓ on all sides:
[tex]( {x}^{3} ) {}^{ \frac{1}{3} } = {95}^{ \frac{1}{3} } \\ \\ {x}^{ \frac{3}{3} } = {95}^{ \frac{1}{3} } \\ \\ x = 4.5629....[/tex]
Approximation / estimation :
[tex]x \approx5[/tex]
What is the area of the square?
24 mm
288 square millimeters
96 square millimeters
312 pi square millimeters
576 square millimeters
Answer:
576 mm²
Step-by-step explanation:
In a square all sides are equal, so area of square = s * s = s²
Area = 24 * 24
Area = 576 mm²
Can someone pleaseee help me <33
I'll do the first five problems to get you started.
===========================================================
Problem 1
Subtraction can be thought of as adding a negative.
So -3 - 6 is the same as -3 + (-6)
We can think of an example involving money
-3 means we're 3 dollars in debt. Then -6 means we go 6 dollars further into debt. Therefore, the total debt is -3 + (-6) = -9 so overall we're 9 dollars in debt.
Answer: -3 + (-6)===========================================================
Problem 2
When subtracting a negative, the two will cancel out to form a positive. This is because negatives are opposite in nature. Two opposites undo one another.
So with all that in mind, something like 10 - (-4) will become 10 + 4
Answer: 10 + 4===========================================================
Problem 3
It's the same idea as the previous problem, but we're dealing with different numbers of course.
Answer: 7 + 2===========================================================
Problem 4
We'll use the ideas mentioned in problem 1. There's not much further to explain here.
Answer: -4 + (-8)===========================================================
Problem 5
Refer back to either problem 2 or problem 3 for a similar example. The negatives will cancel to form a positive.
Answer: -8 + 4What is an equation of the line that passes through the point (-6, -1) and is perpendicular to the line 6x - y = 7?
Answer:
y=-1/6x-2
Step-by-step explanation:
Use the graph to solve the system of linear equations.
2x-y=-2
2x + 4y=8
What is an equation of the line that passes through the point (2,-6) and is parallel
to the line 3 -
2y = 8?
9514 1404 393
Answer:
x -2y = 14
Step-by-step explanation:
The x- and y-coefficients can be the same. The constant needs to change to make the given point satisfy the equation.
x -2y = (2) -2(-6) . . . . . use (x, y) = (2, -6) to find the constant
x -2y = 14
-3/8p=9 how do you isolate p?
Answer:
multiply both sides by 8 then divide by -3
or in one step divide both sides by (-3/8) which is the same as multiplying by
(-8/3)...
-3p = 72
p = -24
Step-by-step explanation:

f(x) = -2x + 4
g(x) = 2x^2 – 2x - 8
Find: (gof)(x)
Answer:
Step-by-step explanation:
[tex]f(x)=-2x+4\\g(x)=2x^2-2x-8\\(g\circ f)(x)=g(f(x))\\=g(-2x+4)\\=2(-2x+4)^2-2(-2x+4)-8\\=2(4x^2-16x+16)+4x-8-8\\=8x^2+(-32x+4x)+(32-8-8)\\=8x^2-28x+16[/tex]

True or False: On a number line, |-8 1/2| and 8 1/2 are the same points
Answer:
True
Step-by-step explanation:
Since the absolute value of a number is just how far that number is from zero all numbers inside an absolute value marking become positive. So, the answer is true.

Determine the sum of the first 10 terms of each geometric series.
a) 4 + 12 + 36 + ...
Answer:
I think the sum of the first 10terms of each geometric series is
4x3=12
= 4+12
12x3=36
=4+12+36
36x3=108
=4+12+36+108
108x3=324
=4+12+36+108+324
324x3=972
=4+12+36+108+324+972
972x3=2916
= 4+12+36+108+324+972+2916
2916x3=8748
=4+12+36+108+324+972+2916+8748
8748x3=26244
=4+12+36+108+324+972+2916+8748+26244
26244x3=78732
=4+12+36+108+324+972+2916+8748+26244+78732=the sum of the geometric series which is = 118,096.

Answer:
(5) 84° and 96° ; (6) 40° and 50°
Step-by-step explanation:
5) Supplementary angles are in the ratio 7 : 8
So 7x + 8x = 180°
15x = 180
x = 180/15
x = 12
The angles are 7x = 7 * 12 = 84° ; 8x = 8 * 12 = 96°
6) Complementary angles are in the ratio 4 : 5
So 4x + 5x = 90°
9x = 90
x = 90/9
x = 10
The angles are 4x = 4 * 10 = 40° ; 5x = 5 * 10 = 50°

13) Rylee had a negative balance of $23 in her bank
account. Her cell phone bill charged this month's balance
of $56. What is Rylee's new balance?
Answer:
-$79
Step-by-step explanation:
She has balance as (-$23)
New balance = -23 - 56
New Balance = -79
Answer:
-$79.00
Step-by-step explanation:
negative 23 minus 56 brings Rylee to negative 79 because more money was taken out of the account after she already had a negative balance.
