If C = t - 5 and B = t^2 + 2, find an expression that equals 2C + 2B in standard
form.
Answer:
t² + t - 3 = 0
Step-by-step explanation:
C = t - 5
B = t² - 2
2C + 2B
= 2(t - 5) + 2(t² + 2)
= 2t - 10 + 2t² + 4
= 2t² + 2t - 6
=> t² + t - 3 = 0
Divide -6.2x10^-4 by 9.75x10^6. Express your answer in scientific notation. Round the coefficient to two decimal places.
Answer:
[tex]-6.36 \times 10^{-11}[/tex]
Step-by-step explanation:
[tex]\dfrac{-6.2\times10^{-4}}{9.75\times10^6}[/tex]
[tex]\implies \dfrac{-6.2}{9.75}\times \dfrac{10^{-4}}{10^6}[/tex]
[tex]\implies \dfrac{-6.2}{9.75}=-6.36\times10^{-1}[/tex]
Apply exponent rule: [tex]\dfrac{a^b}{a^c}=a^{b-c}[/tex]
[tex]\implies \dfrac{10^{-4}}{10^6}=10^{(-4-6)}=10^{-10}[/tex]
[tex]\implies \dfrac{-6.2}{9.75}\times \dfrac{10^{-4}}{10^6}=-6.36 \times 10^{-1} \times 10^{-10}[/tex]
Apply exponent rule: [tex]a^b \times a^c=a^{(b+c)}[/tex]
[tex]\implies -6.36 \times 10^{-1} \times 10^{-10}=-6.36 \times 10^{(-1-10)}[/tex]
[tex]\implies -6.36 \times 10^{-11}[/tex]
[tex]\\ \rm\hookrightarrow \dfrac{-6.2\times 10^{-4}}{9.75\times 10^6}[/tex]
[tex]\\ \rm\hookrightarrow 0.636\times 10^{-4-6}[/tex]
[tex]\\ \rm\hookrightarrow 0.636\times 10^{-10}[/tex]

Keisha drove 100 mile in 2 hours. at this rate how far will she drive in 6 hours?
Answer:
300 miles
Step-by-step explanation:
Since 2 hours multiplied by 3 equals 6 hours, you need to multiply 100 miles by 3. The answer is 300 miles
Answer:
If Keisha drives about 100 miles in 2 hours, then Keisha will drive [tex]\boxed{\bf\:300}[/tex] miles in 6 hours.
Step-by-step explanation:
Given,
Miles driven by Keisha in 2 hours = 100 milesThen,
Miles driven by Keisha in 1 hour:
= Miles driven in 2 hours / 2
= 100/2
= 50 miles
If she goes at this rate,
Miles driven by Keisha in 6 hours:
= Miles driven in 1 hour × 6
= 50 × 6
= 300 miles

b. The given figure is not a rhombus
c. The figure is a square.
d. ∠AEB = 90°
e. m∠EAD = 45°
Which properties of a quadrilateral can be used to find the required dimensions?1. The diagonals of a rhombus bisect each other at right angles
Therefore;
m∠AED = 90° (by definition of right angles)
2. m∠EAD and m∠ADE are complementary angles
Which gives;
m∠EAD + m∠ADE = 90°
m∠ADE = 90° - m∠EAD
Therefore;
m∠ADE = 90° - 67° = 23°
3. The diagonals of a rhombus bisect the angles, therefore;
m∠BAE = m∠EAD = 67°
4. The diagonals bisect each other, therefore;
AE = CE = 5
5. BE = DE = 12
6. JL = 3·x + 4
KM = 4·x - 1
Which gives;
3·x + 4 = 4·x - 1

x = 5
KM = JL = 3 × 5 + 4 = 19
The lengths of the diagonals of rectangle JKLM is 197. JL = 2·x - 6
[tex]KM = \mathbf{\dfrac{3}{2} \cdot x+ 1}[/tex]
Which gives;
[tex]\frac{3}{2} \cdot x+ 1 = 2\cdot x - 6[/tex]
[tex]2\cdot x -\frac{3}{2} \cdot x = 6 + 1 = 7[/tex]
[tex]\dfrac{1}{2} \cdot x = 7[/tex]
x = 2 × 7 = 14
JL = 2 × 14 - 6 = 22
The lengths of the diagonals of rectangle JKLM are 228. W(3, 1), X(3, -2), Y(-5, -2), Z(-5, 1)
WX = 1 - (-2) = 3
YZ = 1 - (-2) = 3
XY = 3 - (-5) = 8
WZ = 3 - 5 = 8
Slope of WX = (1 - (-2)) ÷ (3 - 3) = ∞
Slope of YZ = (1 - (-2)) ÷ (-5 - (-5)) = ∞
Slope of XY = (-2- (-2)) ÷ (3- (-5)) = 0
Slope of WZ = (1- 1) ÷ (3- (-5)) = 0
Therefore;
WX and YZ are perpendicular to XY and WZ
The properties of WXYZ are the properties of a quadrilateral having perpendicular sides.
Given that the sides are not equal, the figure is a rectangle9. W(4, 1), X(1, 4), Y(-2, 1), Z(1, -2)
WX = √((4 - 1)² + (1 - 4)²) = 3·√2
YZ = √((1 - (-2))² + (-2 - 1)²) = 3·√2
XY = √((1 - (-2))² + (4 - 1)²) = 3·√2
WZ = √((1 - (-2))² + (4 - 1)²) = 3·√2
Slope of WX = (4 - 1) ÷ (1 - 4) = -1
Slope of YZ = (-2 - 1) ÷ (1 - (-2)) = -1
Slope of XY = (1 - 4) ÷ ((-2) - 1) = 1
Slope of WZ = (-2 - 1) ÷ (1 - 4) = 1
Therefore;
The lengths of the sides are equal and the sides are perpendicular to each other
Therefore;
WXYZ is a square10. The two column proof is presented as follows;

11. The properties of a rectangle are;
The interior angles are 90°
The diagonals are not perpendicular to each other
In the given figure, the four triangles formed by the diagonals are congruent, therefore;
The angles at the vertex point of the four tringles are equal to each other and therefore, equal to 90°
Therefore;
The diagonals are perpendicular and the given figure is not a rectangleb. The lengths of the diagonals, are equal, therefore;
The given figure is not a rhombuse. The properties of the figure, which includes;
All sides are equal
The interior angles are 90°
The diagonals are equal and bisect each other at 90° indicate that the figure is a squared. The diagonals of a square are angle bisectors of the interior angles
Therefore;
m∠ABE = m∠CBE
m∠ABE + m∠CBE = 90° by definition of complementary angles
Therefore;
m∠ABE = 90° ÷ 2 = 45°
Similarly;
m∠ABE = m∠BAE = 45°
m∠AEB = 180° - (m∠ABE + m∠BAE)
m∠AEB = 180° - (45° + 45°) = 90°e. m∠EAD = m∠BAE = 45° (angles formed by the diagonal AC)

The equation above represents, "Divide 3 by 6 and divide 6 by 12". From both equations to here, you now know what to multiply the numbers by to get your answer.
From here, multiply 3 by 2, and, 6 by 2, to get the equivalent ratio, 6:12.

Two consecutive angles of a parallelogram measure 3x+42 and 9x-18. What are the measures of the angles?
The angles are 81 degrees and 99 degrees
============================================================
Explanation:
Consecutive angles, aka adjacent angles, of a parallelogram always add to 180 degrees. They are considered supplementary.
(angle A)+(angle B) = 180
(3x+42)+(9x-18) = 180
(3x+9x)+(42-18) = 180
12x+24 = 180
12x = 180-24
12x = 156
x = 156/12
x = 13
We can then find the measure of each angle
angle A = 3x+42 = 3*13+42 = 81angle B = 9x-18 = 9*13-18 = 99Then notice that A+B = 81+99 = 180 to confirm the answers.

Answer:
25/9 is the answer
the ratio of the area of PQSR to the area of FGHI is 25/9. The correct answer is:
25/9
To find the ratio of the area of quadrilateral PQSR to the area of quadrilateral FGHI, we can use the property that the ratio of the areas of two similar figures is the square of the ratio of their corresponding side lengths.
Given that quadrilateral PQSR is similar to quadrilateral FGHI, we know that the ratio of corresponding side lengths is QSGH = 5/3.
Now, let's find the ratio of the areas:
Ratio of areas = (QSGH)² = (5/3)² = 25/9
So, the ratio of the area of PQSR to the area of FGHI is 25/9. The correct answer is:
25/9
