Answer:
step 1. DBE ~ ABC
step 2. (x + 5)/4 = (2x + x + 5)/(4 + 3)
step 3. ( x + 5)/4 = (3x + 5)/7
step 4. 7x + 35 = 12x + 20
step 5. 5x = 15
step 6. x = 3.
Answer:
44m
Step-by-step explanation:
X=4
X+5=?...4+5=9
2X+1=...8+1=9
X+9=?...4+9=13
13+13+9+9=44m
Hope this helps as it is my first ever answer :)
Answer:
49.6
Step-by-step explanation:
A = πr2, (Pi r-squared)
A = (3.14)(8)2
A = (3.14) (64)
A = 198.4
but you need to take 1/4th of that since you are only looking at 1/4th of the circle so,
.25 x 198.4 = 49.6
Answer: 16
Step-by-step explanation:
multiplying by negative exponents can be a little tricky. So (1/4x)^-2 becomes 16/x^2 = __/x^2 so the missing number is 16
