Answer:
Okay I'm not thoroughly understanding your question. But here is my answer for BOTH ways.
Step-by-step explanation:
If it's 5 TIMES 3x/8 +2=7
x= 8/3 or x=2.6
If it's 5(3x) OVER 8 in fraction form +2=7
x= 11
Hope this answers your question.
Answer:
<h2>first blank:</h2><h2>c=sqrt(a^2+b^2)</h2><h2>second blank:</h2><h2>c=sqrt((8-2)^2+(-5-3)^2)</h2><h2 />
Step-by-step explanation:
c^2=a^2+b^2
sqrt(c^2)=sqrt(a^2+b^2)
c=sqrt(a^2+b^2)
c=sqrt((x2-x1)^2+(y2-y1)^2)
c=sqrt((8-2)^2+(-5-3)^2)
You got these prime numbers from a factor tree you need to multiple them together to get 2475
The answer is: " 2291 units " .

Explanation:

Formula for "Area of a trapezoid" :
____________________________________________
Area = (1/2) * (base length 1 + base length 2) * height;
or: A = (1/2) * (b + B) * h.
We are missing the value for "b" one of the base lengths.
However, since: A = 68² (given) ; B (the other base length) = 21; and the perpendicular height, "h" = 4 ; we can plug this values into the formula, and solve for "b" ;
________________________________________________
A = (1/2) * (b + B) * h ; ↔ 68² = (1/2) * (b + 21) * 4 ;
↔ <span>4624 = 2 (b + 21) = 2b + 42 ;
</span> ↔ <span>4624 = 2b + 42 ;
</span> ↔ <span>2b + 42 = 4624 ;
Subtract "42" from each side of the equation:
2b + 42 - 42 = 4624 - 42 ;
to get: 2b = 4582 ;
</span>___________________________________________________
Now, divide each side of the equation by: "2" ; to isolate "b" on one side of the equation; and to solve for "b" ;
___________________________________________________
2b / 2 = 4582 / 2 ;
___________________________________________________
to get: b = 2291 units.
