2(x + 4)2 = 20 solve by square roots
Answer:
x = − 4 ± √ 10,
Step-by-step explanation:
2(x + 4)² = 20
=> 2(x + 4) (x + 4) = 20
=> 2x + 8 (x + 4) = 20
=> 2x² + 8x + 8x + 32 = 20
=> 2x² + 16x + 32 = 20
=> 2x² + 16x + 12 = 0
=> Now solve using the quadratic formula:
x = − 4 ± √ 10,
Radical form: − 4 ± √ 10,
Decimal form: -0.84, -7.16

Elena is knitting a design on a sweater. The first row has 10 stitches and each
additional row has 7 stitches more than the row before it. How many stitches are in
the 12th row?
A.74
B.70
C.87
S.86
Answer: 87
Step-by-step explanation:
This will be solved using an arithmetic progression. The formula will be:
= a + (n - 1)d
where,
a = first term = 10
d = common difference = 7
n = 12
Therefore, 12 term will be:
= a + (n - 1)d
= 10 + (12 - 1) × 7
= 10 + (11 × 7)
= 10 + 77
= 87
Therefore, the number of stitches that are in the 12th row will be 87.

Find the measure of the missing angles. Help please
Answer:
< 1 = 92º
< 2 = 24º
< 3 = 35º
< 4 = 35º
< 5 = 81º
Step-by-step explanation:
< 1 = 180 - 88 = 92
< 3 = 64 corresponding angle due to parallel lines
< 2 = 180 - (92 + 64) = 24
< 4 = 180 - (64 - 81) = 35
< 5 = 180 - (64 + 35) = 81
Ashley was given the following problem and she drew a bar diagram to help her solve the problem.
Julie is 5 years younger than her sister, Molly. The sum of their ages is 37. How old is each sister?
Identify the error that Ashley made in creating her diagram and explain to her how to fix it.
Answer:
Julie is 16 years old and Molly is 21 years old.
Step-by-step explanation:
Given that Julie is 5 years younger than her sister, Molly, and the sum of their ages is 37, to determine how old is each sister the following calculation must be performed:
(37 - 5) / 2 = X
32/2 = X
16 = X
(16 + 5) + 16 = X
21 + 16 = X
37 = X
Therefore, Julie is 16 years old and Molly is 21 years old.

Four students explain how to find the measure of ZRST in this diagram.
S
75°
53 R
т
Which student correctly explains how to find the measure of ZRST given the angle measures shown?
A Amy says to use vertical angles to find the measure of ZSRT and add this measure to 75º.
® Brett says to use complementary angles to find the measure of ZSRT and add this measure to 75º.
© Cate says to use vertical angles to find the measure of ZSRT, add this measure to 75º. and then subtract
from 180
D Dylan says to use complementary angles to find the measure of ZSRT, add this measure to 75°, and then
subtract the sum from 180°
Answer:
To find the angle RST we have to first find SRT As the exterior angle adjoined with SRT =53°
so the SRT = Outer angle adjoined with angle SRT
angle SRT = 53° [°.° vertically opposite angles are equal]
Angle SRT + Angle STR + Angle RST = 180°
=>53° + 75° + Angle RST =180°
=> 128° + Angle RST = 180°
=> Angle RST =(180-128)°
= 52°
SO NO. C IS correct what Cate says is absolutely right
(10, 19), (-13, 9) find distance
Answer:
1,043 km
Step-by-step explanation:
hi hope you have a good dayy
Answer:
Distance between points (10, 19) and (-13, 9) is 25.0799
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (10, 19)
Point 2 (xB, yB) = (-13, 9)
Formula : Distance between two points = √(xB − xA)^2 + (yB−yA)^2
Solution :
Distance between two points = √(−13−10)^2+(9−19)^2=
√(−23)^2+(−10)^2
= √529+100
= √629
= 25.0799

◽️a vertex at (0, 96)
◽️the center at (0, 0)
Answer: d and e
Step-by-step explanation:
Edge 2021
The option describes graph 4. a vertex at (0, 96), and 5. the center at (0, 0) from the given equation [tex]\dfrac{y^2}{96^2} - \dfrac{x^2}{40^2} = 1[/tex]
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
The given equation is
[tex]\dfrac{y^2}{96^2} - \dfrac{x^2}{40^2} = 1[/tex]
From the given equation,
a = 40
b = 96
(h,k) = (0,0),
The vertices are at (0,96) and at (0, -96).
The curves open upward and downward.
c² = a² + b²
c² = 40² + 96²
c² = 10816
c = 104
Therefore the foci are at (0, -104) and (0, 104).
Hence, the option describes the graph
4. a vertex at (0, 96) is correct.
5. the center at (0, 0) is correct.

500 gallons of water is being drained at a rate of 4 gallons per hour, If y is the number os gallons of water in the tank after being drained for x hours, which equation represents the situation?
Answer:
4x + y = 500
Step-by-step explanation:
Given:
Volume of water = 500 gallons
Water drained rate = 4 gallon per hour
Find:
Equation
Computation:
Total volume of water left in tank = y
Number of hour water drained = x
So,
Volume of water - Total volume of water left in tank = Water drained rate[Number of hour water drained]
500 - y = 4x
So,
Water drained;
4x + y = 500
Answer:
The correct equation would be y = 4x - 500.Step-by-step explanation:
y = The number of gallons in the tank after being drained for x hours
x = The number of hours that the tank is being drained
500 = The number of gallons in the tank
4 gallons = the number of gallons that are being drained per hour
y = 4x - 500
Correct answer: 0 = 4 (125) - 500
500 / 4 = 125

1. If the function f can be expressed with
the equation f(x) = -x2 – 3x - 10, find the
value of f(-2)
Answer:
f(-2) = -8
Step-by-step explanation:
Plug in x=-2 into the function:
f(x) = -x² - 3x - 10
f(-2) = -(-2)² - 3(-2) - 10
f(-2) = -4 - (-6) - 10
f(-2) = -4 + 6 - 10
f(-2) = 2 - 10
f(-2) = -8
