Let x be the original side length of the square
P=2(l+w)
70=2((2.5+x)+(2.5+x))
70=2(5+2x)
70/2 = 5+2x
35-5=2x
30=2x
15=x
Therefore, the original length of the square was 15"
Hope I helped :)
Answer:
f(x)= -3x+10
Step-by-step explanation:
Answer:
1 : 10.5
Step-by-step explanation:
4 : 42
1 : n
Cross multiply the ratios.
42 × 1 = 4 × n
42 = 4n
42/4 = n
n = 10.5
Log properties or log transformation is;
b ^ x = a , then to solve for the exponent x, log b a = x or read as log a base b = x.
<span> x^19 = y
x = b
a = y
x = 19
log x y = 19 or log y base x = 19</span>
