Which expression represents 4 times as much as 12

Mathematics
1 answer:
Vladimir [108]3 years ago
5 0

Answer:

4x+12

Step-by-step explanation:

An expression is a mathematical sentence that doesn't end in an equal sign. This question is asking for you to find four times as much as 12, but doesn't explain what number or phrase you need to find it for. We would replace the unknown number with the variable X.

I may be confusing this with another subject, so sorry if I am! Hope this helps!

sp2606 [1]

Answer:

a. 15m

b. 7m

Step-by-step explanation:

  • perimeter is the sides added up, there are four sides of a square, and all sides are equal
  • equation s+s+s+s or s•4 (s=sides)
  • so to find the length with the perimeter divide perimeter by 4
  • 60/4=15

  • the area of a square is s²
  • so take the square root of the area

What is the missing length?<br> 10.2 cm<br> a<br> area=51 cm2
AleksAgata [21]

Answer:

a = 10 cm

Step-by-step explanation:

Area of triangle, A = 51 cm²

base, b = 10.2 cm

Let height of triangle be a cm

<em><u>Formula:-</u></em>

A=\dfrac{1}{2}\times a\times b

51=\dfrac{1}{2}\times a\times 10.2

a=\dfrac{51\times 2}{10.2}

a=10

hence, the missing length is 10 cm
