Hey There!
To solve this problem we are going to use distributive property
We are going to distribute the -8 to what's inside of the parenthesis (10x and -3)
10xx-8=-80x
-8x-3=24
were left with
-80x+24
hope this helps!

These triangles are
congruent by the
triangle congruence
postulate [? ]
Answer:
Option A
Step-by-step explanation:
From the picture attached,
In the given triangles ABC and ADC,
m(∠B) = m(∠D) [Given]
AC ≅ CA [Reflexive property]
But in the absence of third property of congruence ΔABC and ΔADC can't be congruent.
Option A is the answer.
-2x-3y-5z=24
-3x-6y-4z=20
-x-6y+6z=-26
Answer equals to - 14
Step-by-step explanation:
6 plus 6 equals to 12
-26 minus 12 equals to -14
Therefore answer equals to minus 14
2/3 + 3/4 + 4/2. If a fraction appears in your answer, it should be in simplified form.

12x = 3y - w, solve for x
Answer:
[tex]x = \frac{3y - w}{12} [/tex]
Step-by-step explanation:
[tex] \frac{12x}{12} = \frac{3y - w}{12} [/tex]
[tex]x = \frac{3y - w}{12} [/tex]

What is the value of x in the right triangle shown? 25 cm 7 cm
Answer:
x = 24
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + b^2 = 25^2
49 + b^2 = 625
-49 -49
b^2 = 576
square root them
b = 24, or x = 24
Hope this helped! Have a nice day! Plz mark as brainliest!!!

Answer: 24
Step-by-step explanation:
A^2 + B^2 = C^2
Solve for c.
a = 11 + 4b – 4c
Answer:
c would be equal to 2948. hope that helps
Answer:
[tex]c=b-\frac{a}{4} +\frac{11}{4}[/tex]
Step-by-step explanation:
[tex]a=11+4b-4c \\a-11=4b-4c\\a-11-4b=-4c\\-\frac{a}{4} +\frac{11}{4} +b=c[/tex]
Rearranging the terms to make it look cleaner, we get:
[tex]c=b-\frac{a}{4} +\frac{11}{4}[/tex]
Quadratic formula 3x^2 - 2x + 5 = 0
Step-by-step explanation:
The given quadratic equation is :
[tex]3x^2 - 2x + 5 = 0[/tex]
We need to solve the given equation. The formula used to solve a quadratic equation is :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have, a = 3, b = -2 and c = 5
So,
[tex]x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(3)(5)}}{2(3)}\\\\x=0.333,4.667[/tex]
Hence, this is the required solution.
Write an equation of the line that passes through the point (-4, -4) and is parallel to 2y - x = -6.
Answer: y=1/2x-2
Step-by-step explanation:
y=mx+b
2y-x=-6
2y=x-6
y=1/2x-3
y-y1=m(x-x1)
y+4=1/2(x+4)
y+4=1/2x+2
y=1/2x-2

PLEASE HELP PLESD PLEDmoon
Answer:
A
Step-by-step explanation:
Given that f(x) = x2 + 1 and g(x) = -3, multiply the functions (gºf)(x).
A) (gºf)(x) = -3x2 - 3
B)(gºf)(x) = -3x2 + 3
C)(gºf)(x) = 3x2 + 3
D)(g. f)(x) = 3x2 - 3
Answer:
[tex](g\cdot f) = -3x^2-3[/tex]
Step-by-step explanation:
[tex]f(x) = x^2 + 1[/tex]
[tex]g(x) = -3[/tex]
The problem state to multiply the function [tex]f[/tex] and [tex]g[/tex] so the symbol seems to be incorrect.
We actually want to calculate
[tex]g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3[/tex]
Note
[tex]g\circ f(x)=g(f(x))=g(x^2+1)=-3[/tex]
Riku says that a and b have the same value in the equations 0.75(a−2)=5.25 and 34b−32=214. Is Riku correct?
Answer:
riku is is wrong
Step-by-step explanation:
divide each term by 0.75
a-2=5.25/0.75
a-2=7
a=9
34b= 214+32
34b=246
b=123/17
or 7.235
therefore both answers are different
