Answer:
a+3
Step-by-step explanation:
You cannot go any further in answering this question. These two terms are not like terms so they cannot be combined. Therefore, the answer is just a+3 itself.
Answer:
(2A)/h -a =b
Step-by-step explanation:
A= [h(a+b)]/2 I rewrote the formula, because h and a+b are in the numerator.
2A=h(a+b) Multiply both sides of equation by 2
(2A)/h= a+b Divide both side by h
(2A)/h -a= b Subtract a from both sides
Oh yeah, now give me branliest.
Answer:
y = 1/2 (2)x
Step-by-step explanation:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3 Solve each equation for a.
2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3
Cross multiply: 2b3 = 4b2 Divide both sides by b2
2b = 4 a = 2/4 = 1/2
b = 2
