Answer:
A
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × width
= (2x + 10)(2x + 6) ← expand using FOIL and equate to 140
= 4x² + 12x + 20x + 60 = 140
= 4x² + 32x + 60 = 140 ( subtract 140 from both sides )
4x² + 32x - 80 = 0
Answer:
A: 4x² + 32x - 80 = 0
Step-by-step explanation:
Length = 2x + 10 inWidth = 2x + 6 inArea = 140 in²Formula
Area (rectangle) = Length x WidthSolving :
140 = (2x + 10)(2x + 6)2x(2x) + 10(2x) + 2x(6) + 10(6) = 1404x² + 20x + 12x + 60 = 1404x² + 32x - 80 = 0The correct option is A13. Which equations are true? Select All that apply

Answer:
214°
Step-by-step explanation:
The external angle (marked 34°) is equal to half the difference of the arcs ACB and AB.
34° = 1/2(ACB -AB)
Together, the two arcs form a complete circle of 360°, so we have ...
34° = 1/2(ACB -(360° -ACB)) = 1/2(2ACB -360°)
34° = ACB -180° . . . . . . . . . . . . simplify
180° +34° = ACB = 214° . . . . . add 180°
The measure of arc ACB is 214°.

In the figure shown, what is the measure of angle 2, if
angle 4 = 120 degrees?
Answer:
The measure of angle 2 = 120°
Step-by-step explanation:
angles 2 and 4 are two vertically opposite angles therefore they are equal to each other.
In other words,
angle 2 = angle 4 = 120
Write an equation in point-slope form of the line that passes through the point (-6,6) and has a slope of m=3/2
Answer:
y-6=(3/2)(x+6)
Step-by-step explanation:
Given:
slope = m = 3/2point = (x1,y1) = (-6,6)Point-Slope:
[tex]\displaystyle \large{y-y_1=m(x-x_1)}[/tex]
Substitute m = 3/2, x1 = -6 and y1 = 6:

The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot φ as 1.707
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees.
Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.
oposite side = 29 m
adjacent side = 49.5 m
hypotenuse side = 57.4 m
Therefore,
cot φ = 1 / tan φ
Hence,
tan φ = opposite / adjacent
Therefore,
cot φ = adjacent / opposite
cot φ = 49.5 / 29
cot φ = 1.70689655172
cot φ = 1.707

The radius of the large sphere is times longer than the radius of the small sphere. how many times the volume of the large sphere is the volume of the small sphere?
The volume of the large sphere shown in the image is, 1/27 times the volume of the small sphere.
What is of volume of sphere?Volume of sphere is the amount of quantity, which is obtained by the it in the 3 dimensional space.
The volume of the sphere can be given as,

The experiment is blindeded because the scientist know which treatment group each subject is in.
What is experiment?Experiment is the scientific approach to determine the properties of some sample by doing some research on it eg. By adding another material, or determination of hypothesis.
What is hypothesis?Hypothesis is the assumption which is made under some evidence which can be proceed further verification or by doing experiment on it.
From the question it is clear that the scientist wants to meassure the effect of apple cider vinegar subject on the blood sugar level.
So here the effect of apple cider vinegar subject on the blood sugar level is hypothesis.

I am going to solve by elimination.
Start by subtracting one equation from the other

Now solve for x
[tex]0=-\frac{1}{2} x+6\\0-6=-\frac{1}{2} x+6-6\\-6=-\frac{1}{2} x\\(-6)(-2)=(-2)(-\frac{1}{2} x)\\12=x[/tex]
