Good evening ,
Answer:
B. 24
Step-by-step explanation:
y and x have a proportional relationship, and y = 24 when x = 16
then
y÷x = 24÷16 = 1.5
Since y=36 then
36÷x = 1.5
then
x = 36÷1.5 = 24.
:)
Given: y=x^3 and y=343
So, 343=x^3
Cube root both sides which will get rid of the cube on the right side of the equation
You are left with the cube root of 343. Which equals 7.
7*7*7=343
X=7
Answer: If the hypotenuse is 7, the other 2 sides are 
0r about = 4.95
Step-by-step explanation: in a 45-45-90 triangle, the legs are equal.
a² + b² = c² . 2(a²) = 49 a² = 49/2
So find the square root of 24.5
=4.949747468 .round to 4.95
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>
