$=(a^2-10a)-(b^2+6b) +16$
$=[(a^2-2(5)a+25)-25]-[(b^2+2(3)b+9)-9]+16$
$=(a-5)^2-25-(b+3)^2+9+16$
$=(a-5)^2-(b+3)^2$

Answer:
<em> SSS</em><em> can be used to prove that the given triangles are congruent.</em>
Step-by-step explanation:
In the given two triangles ΔADC and ΔABC,
- AD = AB = 7 units,
- CD = BC = 8 units,
- AC is common to both triangles,
Hence, ΔADC ≅ ΔABC by Side-Side-Side (SSS) congruence.
SSS congruence-
If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
Answer:
<u>Given</u>: base = 10.4ft, height = 12.5
Area of octagon = 8(1/2 × b × h)
- 8(1/2 × 10.4 × 12.5)
- 520ft²
Volume of pool = 520ft² × 3ft
Now, 1 cubic ft takes 7.5 gallons to fill.
Therefore, 1560 cubic ft takes,
So, <u>Correct choice</u> - [D] 11,700.
Answer:
About 19.45%
Step-by-step explanation:
First set the fraction equal to x over 100 ———- (70/360)=(x/100)
cross multiply———- 70 * 100 = 7000 360 * x = 360x
solve for x —————- 7000=360x
7000/360= 19.44444444
Round ——- x=19.45
OR
Divide fraction ———— 70/360 = 0.1944444444
Next, convert to percentage by moving decimal 2 places to the right ——
019.44444444
Round ————- = 19.45
