7(8-x) = 210

Answers

Answer:

x=266

Step-by-step explanation:

I'm sure if this is correct but this is how I did it seven times eight is 56 and you have to subtract that number by x so x would have to be bigger so it would be 56 minus 266

will give you 210

Answer:

x=-22

Step-by-step explanation:

7(8-x)=210

you would use the distributive property

56-7x=210

then subtract both sides by 56

-7x=154

then divide both sides by -7

x=-22

Helllllp

Answers

9514 1404 393

Answer:

  74

Step-by-step explanation:

The recursive definition is for an arithmetic sequence with a first term of -6 and a common difference of 4.

The general term of such a sequence is ...

  a(n) = a(1) +d(n -1)

This sequence is ...

  a(n) = -6 +4(n -1) = 4n -10

Then for n = 21, the term is ...

  a(21) = 4(21) -10 = 84 -10

  a(21) = 74

Squares and triangle

From the given square, the triangle AEB is a right triangle.

A right triangle has one of its angles to be 90 degrees.

According to triangles AEB, m<EAB = m<ABE = 45 degrees

m<AEB = 180 - (45+45)

m<AEB = 180 - 90

m<AEB = 90 degrees

Hence the measure of m<AEB is 90 degrees

Joe’s Coffee is having a stained glass window installed on their front door. Approximately how much glass will be needed to create the stained glass window?
PLSS USE STEPSSS!!!!
A) 2.4
B) 9.6
C) 11
D) 38.5

Answers

Correct option :

[tex]\color{plum}\tt \: D) 38.5 [/tex]

Steps to derive correct answer :

Diameter of the stained glass window Joey needs = 3.5

Area of the window = quantity of glass Joey needs

Area of the window :

[tex] = \tt\pi {r}^{2} [/tex]

[tex] = \tt3.14 \times 3.5 \times 3.5[/tex]

[tex] =\tt 3.14 \times 12.25[/tex]

[tex] =\tt 38.46[/tex]

38.46 can be rounded off to 38.5.

Therefore, quantity of glass needed to make the stained glass window = 38.5

Solve for t:

t = [tex]x^{2}[/tex]

Plug in t:

y = 4([tex]x^{2}[/tex] ) +3
