Answer:
<u>∗ = 0.4x³</u>
Step-by-step explanation:
(15y + ∗)² = 225y²+12x³y+0.16x⁶
<u>Note:</u>
225y² = 15y * 15y = (15y)²
12x³y = 2 * 15y * 0.4x³
0.16x⁶ = 0.4x³ * 0.4x³ = (0.4x³)²
So, by factoring the right hand side:
225y²+12x³y+0.16x⁶ = (15y + 0.4x³)²
By comparing the left hand side with (15y + 0.4x³)²
<u>So, ∗ should be replaced with the monomial 0.4x³</u>
Answer:
QT = RT
Step-by-step explanation:
When drawing triangle PQR the perpendicular bisector cuts the triangle in half, which results in two sides that are congruent. This makes QT and RT congruent.
Answer:
The whole tank cost $55.13
Step-by-step explanation:
All you have to do is multiply the fraction and cost, to ge thte total cost
15 3/4 also equals 15.75 (it will be easier to multiply two fractions)
now each gall of the 15.75 costs 3.50 so we multiply the number of gallons by the cost
15.75 x 3.50 = 55.125
but now we must round since there isnt .125 cents
so
55.13 is the cost
