Answer:

Step-by-step explanation:

Hello,

$(x-40)^2=36=6^2\\\\ \sqrt{(x-40)^2}=6\\\\ |x-40|=6\\\\ x-40 = 6 \ or \ x-40 = -6\\\\x=46 \ or \ x = 34$

Hope this helps

Let m = X^2 + 3.

Tpy6a [65]

The Equation in terms of m, m^2+7m+10=0

What is substituting in the equation ?

substituting means changing or replacing the values in the given equation.

Calculation:

Given equation is (x^2+3)^2+7x^2+21=-10

and m= X^2 + 3.

make the given equation in the form X^2 + 3,

now,

(x^2+3)^2+7x^2+21=-10

(x^2+3)^2+7(x^2+3)=-10

where,

X^2 + 3= m

after putting the value or replacing the values

we get, m^2+7m=-10

m^2+7m+10=0

the above equation is in the form of "m".

The Equation in terms of m, m^2+7m+10=0

Monica has a 24-inch square frame. There are 4 equal sides. She paints 3/4 of one side of the frame blue. What fraction of the f

IgorC [24]

Answer:

3/16

Step-by-step explanation:

Monica has a 24-inch square frame.

There are 4 equal sides.

Hence, length of each side=24/4 inch

= 6 inch

She paints 3/4 of one side of the frame blue.

i.e. she paints $\dfrac{3}{4}\times 6$ inch

Total part to be painted=24 inch

Hence, fraction of the frame Monica painted blue is:

$\dfrac{3\times 6}{4\times 24}\\ \\= \dfrac{3}{16}$

Prove that DJKL~ DJMN using SAS Similarity Theorem. Plot the points J (1,1), K(2,3), L(4,1) and J (1,1), M(3,5), N(7,1). Draw DJ

dolphi86 [110]

Answer and Step-by-step explanation: The triangles are plotted and shown in the attachment.

SAS Similarity Theorem is by definition: if two sides in one triangle are proportional to two sides of another triangle and the angles formed by those sides in each triangle is congruent, the triangles are similar.

For the triangles on the grid, we know that ΔJKL and ΔJMN have a congruent angle in J as shown in the image. To prove they are similar, we find the slope of sides KL and MN:

Slope of KL:

slope = $\frac{y_{K} - y_{L} }{x_{K} - x_{L} }$
