just need help

Answer:

9 sq. units

Step-by-step explanation:

dimensions of rectangle are (7-3),(8-3)

or 4,5

area of rectangle=4×5=20

area of bottom Δ=1/2×4×2=4

area of top Δ=1/2×3×3=9/2

area of right triangle=1/2 ×5×1=5/2

area of Δ HIJ=20-(4+9/2+5/2)

=20-(4+14/2)

=20-(4+7)

=9 sq. units.

or area of triangle =1/2

| 3  5 |

| 7  3 |

|6   8 |

|3   5 |

=1/2[(9-35)+(56-18)+(30-24)]

=1/2[-26+38+6]

=1/2[-26+44]

=1/2(18)

=9 sq. units.

Answer:

35 degrees

Step-by-step explanation:

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side

sum of angles in a triangle = 180

180 - 110 = 70

since 2 angles would be equal

70 / 2 = 35

The true statements concerning trapezoid RSTU are:

STUT

CABRS

DRS UT

Based on the given information that Trapezoid ABCD has been translated down and to the right to form trapezoid RSTU, we can determine the relationships between the corresponding sides and angles of the two trapezoids.

Given:

AB || DC

Based on the parallel lines, we can infer the following relationships:

Corresponding sides are parallel:

RS || UT (corresponds to AB || DC)

ST || RU (corresponds to BC || DA)

Corresponding angles are congruent:

∠R ≅ ∠A

∠S ≅ ∠B

∠T ≅ ∠C

∠U ≅ ∠D

From these relationships, we can determine the following statements that are true concerning trapezoid RSTU:

STUT (corresponds to ABCD): The bases of the trapezoids are parallel, so the order of the vertices remains the same.

CABRS (corresponds to DCBA): The corresponding angles in trapezoid RSTU and trapezoid ABCD are congruent.

DRS UT (corresponds to ABDC): The order of the vertices is reversed, but the parallel sides and corresponding angles remain the same.

Therefore, the true statements concerning trapezoid RSTU are:

STUT

CABRS

DRS UT

Answer:

3)

Each stripe is 1/18 yards thick, and the fence post if 5/6 yards. Therefore, we have to find how many 1/18s can go into 5/6. Thus, this is a matter of division, and we do 5/6 divided by 1/18 to find how many stripes we can have.

5/6 ÷ 1/18 = 5/6 * 18 = 15

Thus, the answer is D.

4) A is 3, which means we substitute all the "a"s in the expression for 3. Thus we have:

99 - 7[tex]a^{2}[/tex]

99 - 7(3)^2

99 - 7(9)

99 - 63 = 36

Therefore, it is 36.

Answer:

A. x^2+3x-4

B. 6x^2-5x+1

Answer:

A: x^2+3x-4

B: 6x^2 -5x +1

Step-by-step explanation:

Alright, so for this, use the FOIL method, by multiplying the terms of each question in this order:

First

Outer

Inner

Last

So with the first question, lets do this:

(x+4)(x-1)

F: x * x = x^2

O: x * -1 = -x

I: x * 4 = 4x

L: 4 * -1 = -4

Then combine the like terms together:

x^2 + -x + 4x -4

A: x^2+3x-4

With the next one, same deal:

(2x-1)(3x-1)

F: 2x * 3x = 6x^2

O: 2x * -1 = -2x

I: 3x * -1 = -3x

L: -1 * -1 = 1

Then combine them up:

6x^2 -2x -3x +1

B: 6x^2 -5x +1

All done!

Answer:

12

Step-by-step explanation:

Please write this function as P(x) = x^3 + 7x^2 + 4x + 0.  This third order function has four coefficients.  We set up synthetic division with -2 as the divisor:

-2   /   1    7    4    0

              -2   -10  12

     ----------------------

        1      5     -6  12

The remainder is 12.  Accordng to the Remainder Theorem, the value of P(x) at x = -2 is 12.

Answer:

See solution below

Step-by-step explanation:

The centre of the circle will be the midpoint of both coordinate

Given the coordinates P(-7, -10) and Q = (3,2)

X = x1+x2/2

X = -7+3/2

X = -4/2

X = -2

Y = y1+y2/2

Y = -10+2/2

Y = -8/2

Y = -4

Hence the centre is at (-2, -4)

The distance between the coordinates will be the diamter

PQ =√(3+7)² + (2+10)²

PQ =√(10)² + (12)²

PQ = √100+144

PQ =√244

radius = √244/2

Get the equation

(x-a)² + (y-b)² = r²

(x -(-2))² + (y-(-4))² = (√244/2)²

(x +2)² + (y+4)² = (244/4)

(x +2)² + (y+4)² = 61

This gives the required equation

Answer:

SA ==736^2

Without unit = 736^2

Step-by-step explanation:

Start with base of a triangle face

Base = 12 Height = 8

1/2 x 12 x 8 =  48  cm^2      one side face surface area

48 x 2 = 96 cm^2               two side face surface area bold

----

Sides

10 x 20 = 200 cm^2            one side face surface area

200 x 2 = 400 cm^2           two side face surface area bold

-----

base 20 x 12 = 240 cm^2    single base. bold

Add up those values in bold =  240 + 400 + 96 =736 cm^2

Answer:

3282 m^2

Step-by-step explanation:

volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

r = (450,000 x (3/2) x(1/3.14)) ^1/3

r = 45.72

Area of a semicircle = 1/2 x n x r^2

1/2 x 45.72^2 x 3.14 = 3282 m^2

Answer:

area of the square=18×18

area of the shaded region=324-254.502

=69.498 cm²

Answer:

x = {-8 - √10, -8 + √10}     exact answer

x = {-11.16, -4.84}     decimal approximation

Step-by-step explanation:

2(x + 8)²+ 9 = 29

Subtract 9 from both sides

2(x + 8)² = 20

Divide both sides by 2

(x + 8)² = 10

Take the square root of both sides

x + 8 = ±√10

Subtract 8 from both sides

x = -8 ± √10

x = {-8 - √10, -8 + √10}     exact answer

x = {-11.16, -4.84}     decimal approximation
