Answer:
x = [tex]2\sqrt{2}[/tex] (or [tex]\frac{2\sqrt{2} }{1}[/tex] if it needs to be represented as a rational denominator)
Step-by-step explanation:
We know that;
1.) This triangle is equilateral, and because of the line segment it's divided into 2 right triangles.
2.) The base of the whole triangle would be 4, and the base of the right triangle would be 2, since the base is cut in half with a mid point.
Therefore we can say;
A² + B² = C²
x² + 2² = 4²
x² + 4 = 16
x² = 16 - 4
x² = 8
x = [tex]\sqrt{8}[/tex]
Simplifying this further would be;
[tex]\sqrt{8}[/tex] = [tex]\sqrt{4} * \sqrt{2}[/tex]
[tex]\sqrt{8}[/tex] = [tex]2\sqrt{2}[/tex] (or [tex]\frac{2\sqrt{2} }{1}[/tex] if it needs to be represented as a rational denominator)
Hope this helps!

Which of the following is a constant in this expression?
Which of the following lists all the coefficients in this expression?
Answers
Answer:
constant: 4
coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)
Step-by-step explanation:
coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.
constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
therefore, 4 is a constant.

write an equation then find the angle measure for A. 25 points and brainliest.
Answers
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4 + 3x + 3x + 14 + 90 = 180 , simplify left side
108 + 6x = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
Then
∠ A = 4 + 3x = 4 + 3(12) = 4 + 36 = 40° → A

Answer:

Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2+1\text{ and } g(x)=x-4[/tex]
And we want to find:
[tex](f\circ g)(10)[/tex]
This is equivalent to:

Find g(10) first:
[tex]g(10)=(10)-4=6[/tex]
Substitute:
[tex]f(g(10))=f(6)[/tex]
Evaluate f(6):
[tex]f(6)=(6)^2+1=37[/tex]

A = 2(7*10+10*5+7*5)
A = 310

A = 136
Now the squares that connect both, 4*3
Since you have 1 on each rectangle, the total area for this is 24
add 310 + 136 and substract 24

The solution to the multiplication of surds (2√3) × (3√2) is; 6√6
We want to find; √12 × √18Let us break each of them into the factors to get;
√12 × √18 = √(4 × 3) × √(9 × 2)
Now,this can be expressed as;(√4 × √3) × (√9 × √2)
Simplifying this further gives;
(2√3) × (3√2)
Now, in surds, we know that;a√b × p√q = ap√bq
Applying the surd rule above to our question gives;(2√3) × (3√2) = 6√6

Leo is buying milk for his family for a week. He said he bought 7 kilograms of milk. Is his answer reasonable? Explain.
Answers
Answer:
First, we know that a single liter of milk weighs around 1.032 kg.
Then 7 kilograms of milk is equivalent to (almost) 7 liters of milk.
Now, this is reasonable?
Well, for a typical person, the consumption is between 0.5L and 0.75L
So 7kg of milk may less of what a typical family consumes in a week, but is not an outlier (for example, 30kg of milk or 1kg of milk per week are outliers, which are "nonreasonable") so 7 kg is a reasonable amount of milk.
Now, if the question only refers to the units he used (kg instead of liters) this does not matter, as we know, mass and volume are two different, but equivalent, ways of describing a known matter, as these are related by the density:
Density = mass/volume.
So, for a known material, if you know the mass that you have, you also know the volume.
Then using kg is reasonable in this situation.
The equations in the system below are equivalent.
y = 2 (x + 4). Y = 2 x + 8
How many solutions does the system have?
