Just add the same sides and angles
What do you need help with
The answer is B. A squared + B squard = C squared.
-5 (2u+10)=2 (u_7) apply distributive property
-10u-50=2u-14 collect like terms
-10u-2u=50-14 when you move the number to the other side sign change
-12u =36 to get rid of 12 divide 12 on both sides
-12u/-12= 36/-12
U= -3
For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
Answer: a system of linear inequations that represents the situation is:
