Which of the following is the solution to the quadratic equation
x2−10x+21=0 ?
Step-by-step explanation:
the answer is the image above
Answer:
x=3 and x=7
Step-by-step explanation:
x2 - 10x + 21=0
a=1, B=-10, c=21
delta= b2 - 4(ac)
if delta >0 => have two answer
x1= -b - _/delta / 2a = -(-10) - _/16 / 2.1 = 3
x2= -b + _/delta /2a = -(-10) + _/16 / 2.1= 7
If you have 1/4 of a pie left and you give away 5/8 how much pie do you have left
Answer:
You cannot give away more than you have. You have no pie left.
Step-by-step explanation:
1/4 - 5/8
Multiply 1/4 by 2 to get a common denominator in order to subtract.
2/8 - 5/8
= -3/8
You can't have -3/8 of a pie.
Therefore, you have no pie left.

The measure of segment AB with a(-4,-9) and B(4, -3) is
Answer: 10
Step-by-step explanation:
using [tex]d = \sqrt{(x_{1}-x_{2} )^{2} +(y_{1}- y_{2} )^{2} }[/tex] when [tex]P_{1} =(x_{1} ,y_{1} )[/tex] and [tex]P_{2} = (x_{2}, y_{2})[/tex]
so [tex]d = \sqrt{((-4)-4)^{2}+((-9)-(-3))^{2} }[/tex]
[tex]d = \sqrt{(-4-4)^{2}+(-9+3)^{2} }[/tex]
[tex]d = \sqrt{(-8)^{2}+(-6)^{2} }[/tex]
[tex]d = \sqrt{64+36}[/tex]
[tex]d= \sqrt{100}[/tex]
[tex]d = 10[/tex]

There are 5×3 = 15 boys.
There are 4×3 = 12 girls.
use the distributive law to factor.
16m + 6n
Using the distributive law to factor, the expression becomes 16m + 6n = 2(8m + 3n)
GIven three integers A, B and C, according to the distributive property;
A(B+C) = AB + BC
Given the expression 16m + 6n
First, we need to get the factors of both terms
16m = 2 * 8 * m
6n = 2 * 3 * n
From both factors, we can see that 2 is common to both of them. Hence using the distributive law to factor, the expression becomes;
16m + 6n = 2(8m + 3n)
