Jermaine draws a triangle with the following dimensions:
• Height: 15 centimeters
• Base: 16 centimeters
What is the area of the triangle?
? cm2​

Answer:

33

Step-by-step explanation:

Supplementary angles add up to 180 degrees. So, 4x + (x+15) = 180

5x+15=180

5x=165

x=33

Answer:

A.

Step-by-step explanation:

64/4=16  80/5=16 They are multiplied by the same number so it is A

Answer:

3220 cm²

Step-by-step explanation:

Lets find the area of the two triangles

I am making a modification:

Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2

Area of triangles = 15 cm x 28 cm = 420 cm²

Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²

Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²

Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²

Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²

If my answer is incorrect, pls correct me!

Answer:

4 / 3

Step-by-step explanation:

tan x = opposite / adjacent

tan x = AB / AC

tan x = 4 / 3

{ x = theta ]

Answer:

  tan(θ) = 4/3

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Tan = Opposite/Adjacent

Then ...

  tan(θ) = AB/AC

  tan(θ) = 4/3

Step-by-step explanation:

|3x - 4| = 6

3x-4 = 6 or 3x-4 = -6

3x=6+4 3x=-6+4

3x=10 3x = -2

x= 10/3 x = -2/3

so, x1= 10/3 or x2 = -2/3

Answer:

D. 174 m^2

Step-by-step explanation:

the formula for area for squares is l*w so 12*12= 144

then for the triangle the formula is l*w/2

so 12*5=60/2=30

144+30=174

Given:

In triangle ABC, AE is the angle bisector.

[tex]AB=4, BE=2, AC=x, CE=3[/tex]

To find:

The value of x.

Solution:

According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side of the triangle into two parts. These two parts are proportional to the other two sides of the triangle.

Using the angle bisector theorem, we get

[tex]\dfrac{AB}{AC}=\dfrac{BE}{CE}[/tex]

[tex]\dfrac{4}{x}=\dfrac{2}{3}[/tex]

On cross multiplication, we get

[tex]4\times 3=2\times x[/tex]

[tex]12=2x[/tex]

Divide both sides by 2.

[tex]\dfrac{12}{2}=x[/tex]

[tex]6=x[/tex]

Therefore, the value of x is 6.

Answer:

y = 8 - 5x, y(-2) = 18, y(0) = 8, y(3) = -7

Step-by-step explanation:

y + 5x = 8

y = 8 - 5x

y(-2) = 8 - 5*(-2) = 8 + 10 = 18

y(0) = 8 - 5*(0) = 8 - 0 = 8

y(3) = 8 - 5*(3) = 8 - 15 = -7

Answer:

Step-by-step explanation:

Multiply 7*4 and sqrt8*sqrt5, resulting in 28sqrt40.

sqrt40 can be simplified to 2sqrt10.

Therefore, 10 stays under the sqrt and 2 comes out.

2*28=56.

Therefore, the answer is 56sqrt10.

Answer:

x=13° & y=74°

Step-by-step explanation:

y=74°(cointerior angle r equal)

now,

y=4x+22(vertically opposite angles equal)

Answer:

x = 21

Step-by-step explanation:

The 74 angle and y angle are supplementary which means they add up to 180 degrees, so 180 - 74 = 106

Then you know that y is equal to 4x + 22

so then you just set 4x + 22 equal to 106

then you subtract 22 from both sides which leaves you the equation 4x = 84

then you divide 84/4 which equals 21

Answer:

Doesn't fit

Step-by-step explanation:

There are 2.4litres in the beaker if you count the lines; they increment by 0.4 litres each. The volume of the storage container is 20 x 15 x 7 = 2100 cm^3 (cm cubed). 1 cm^3 = 1 ml; the cube can hold 2100 mL which is 2.1 litres, which is less than the 2.4 litres in the beaker, therefore it will not fit.

This beaker will not fit into this rectangular food storage container.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since,  There are 2.4litres in the beaker, they increment by 0.4 liters each.

Hence, The volume of the storage container is,

⇒ 20 x 15 x 7

⇒ 2100 cm³

Since, Here we have;

1 cm³ = 1 ml

So, The cube hold 2100 mL which is 2.1 liters,

Clearly, It is less than 2.4 liters in the beaker.

Thus, This beaker will not fit into this rectangular food storage container.

Answer:

Lets say there's a quadratic equation → ax² + bx = -c

Lets make one side zero which gives → ax² + bx + c = 0

From the above equation ,

For example :- x² - 12x = -35.

Lets make one side zero → x² - 12x + 35 = 0 . Now, lets break -12x into two real numbers 'p' & 'q' such that p + q = -12x & pq = 35. Prime factors of 35 are 1 , 5 & 7. If we take 5 & 7 as 'p' & 'q' then p + q = 5 + 7 = 12. but as we need -12 , the values of 'p' & 'q' are -5 & -7.

⇒ [tex]x^2 -5x - 7x + 35 = 0[/tex]

⇒ [tex]x(x - 5) - 7(x - 5) = 0[/tex]

⇒ [tex](x - 5)(x - 7) = 0[/tex]

⇒ [tex]x = 5 \: or \: 7[/tex]

Lets take another example :- x² + 4x = 1.

Lets make one side zero → x² + 4x - 1 = 0 . Now , lets split +4x into into two real numbers 'p' & 'q' such that p + q = +4x & pq = -1 . Prime factors of 4 are 1 & 2 only. But there's no such combination of its primes such that their sum would be equal to 4. So, the quadratic equation can't be solved by factorisation method. Now, lets bring -1 to Right Hand Side & try solving by completing squares method.

⇒ [tex]x^2 + 2 \times x \times 2 + 2^2 = 1 + 2^2[/tex]

⇒ [tex](x + 2)^2 = 1 + 4 = 5[/tex]

⇒ [tex]x + 2 = +\sqrt{5} \: \: or \: -\sqrt{5}[/tex]

⇒ [tex]x = (\sqrt{5} - 2) \: or \: (-\sqrt{5} -2)[/tex]

Conclusion:

First try making one side zero and try to solve the equation by factorisation method. If it got factorised , then you are done and if it didn't get factorised , then solve it by completing squares method.

Answer:

I'm assuming we're asking about the difference between:

[tex]ax^2 + bx + c = 0[/tex]

and

[tex]ax^2 + bx = -c[/tex]

Let's preface this by stating the obvious: there's no actual difference. Both equations are equivalent.

Now, it has a lot to do with our goal. Sometimes our goal is to write an equation concisely (then the "no-zero" way uses less characters), and sometimes we're dealing with a quadratic function of

[tex]y = ax^2 + bx + c[/tex]

in the second case, we wouldn't write

[tex]y - c = ax^2 + bx[/tex]

because it'd be confusing. That means that when we're looking for y=0 points of a quadratic equation, the way to convey that goal is that we're looking for the point where [tex]ax^2 + bx + c = 0[/tex] - so we preserve the structure of the quadratic function.
