18/2,27/3,36/4,45/5,54/6,63/7,72/8, and 81/9 can be some.
Answer:
Roots: 2, -8
Step-by-step explanation:
- <em>Use of formula: a^2+2ab+b^2= (a+b)^2</em>
<u>Below steps show how to complete square and solve the equation:</u>
- r^2 + 6r = 16
- r^2 + 2*3*r = 16 <em>adding below missing part of equation, and completing square</em>
- r^2 + 2*3*r + 3^2= 16+ 3^2
- (r+3)^2= 25
- r+3= ± 5
- r= - 3 ± 5
- r= 2, r= - 8
<u>Roots are</u> 2 and - 8
The answer is 25 because u divide 15 divided by 37.5 which equals 25
Answer:
a and e
Step-by-step explanation:
because for e it multiplies by2 and so does a
im 90% sure
Solution for 4y=2(y-5)-2 equation:
Simplifying 4y = 2(y + -5) + -2 Reorder the terms: 4y = 2(-5 + y) + -2 4y = (-5 * 2 + y * 2) + -2 4y = (-10 + 2y) + -2 Reorder the terms: 4y = -10 + -2 + 2y Combine like terms: -10 + -2 = -12 4y = -12 + 2y Solving 4y = -12 + 2y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-2y' to each side of the equation. 4y + -2y = -12 + 2y + -2y Combine like terms: 4y + -2y = 2y 2y = -12 + 2y + -2y Combine like terms: 2y + -2y = 0 2y = -12 + 0 2y = -12 Divide each side by '2'. y = -6 Simplifying y = -6
