Your answer would be
70a + 21b
Answer:the record low temperature in Alaska = -80°F
Step-by-step explanation:
Step 1
Let the temperature in Alaska be = x
such that the temperature in Hawaii be -0.15 times temperature in Alaska = -0.15 x.
Step 2
IF the record low temperature in Hawaii is 12°F.
Alaska = ??
We know that
Hawaii= -0.15 x temperature Alaska ( 0.15 x)
12°F=-0.15 x temperature Alaska(x)
Temperature of Alaska, x = 12°F/-0.15
= -80°F
Answer: (B) 1.12
Step-by-step explanation:
8 weeks = 56 days
56 days x 20 grams = 1120 grams
1120 grams = 1.12 kilograms
So megan is four years younger than her aunt
m+4=a
or
m=a-4
the sum of their ages is at least 40
m+a<u>></u>40
subsitute a-4 for m
a-4+a<u /><u>></u>40
combine like terms
2a-4<u>></u>40
the answer is the third from the top
Answer:
b² +12b +32 = (b+4)(b+8)
Step-by-step explanation:
The product of binomial factors (x+a) and (x+b) is ...
(x+a)(x+b) = x² +ax +bx +ab
= x² + (a+b)x + ab
That is, the coefficient of x is the sum of factors of the constant term.
In order to determine "a" and "b", you can look at the factors of 32 and see which pair has a sum that is 12.
32 = 1×32 = 2×16 = 4×8
The last factor pair has a sum that is 12, so your factorization can be
b² +12b +32 = (b+4)(b+8)
