A) x^2 +x -30 = 0 is factored by looking for two factors of 30 that differ by 1. We know ... 30 = 1*30 = 2*15 = 3*10 = 5*6The last two factors differ by 1, so we can factor the trinomial as (x +6)(x -5) = 0
b) The solutions are found by finding values of x that make these factors zero. The only way the product will be zero is if one or more of the factors is zero. x + 6 = 0 x = -6 . . . . . subtract 6
x - 5 = 0 x = 5 . . . . . add 5
The solutions are x = -6 or x = 5These are the values of x that will satisfy the equation (make it true). What they mean depends on the meaning of the variable and the situation the equation is a model of.
Answer:
1 quarter pound = 0.25 of a pound.
Give that:
Total amount of ground beef = pound
From 3.5 pound of beef we have to make burgers using 0.25 pound of beef in one burger
We have to find how many burgers can be made:
We have to divide 3.5 pound by 0.25 pound
i.e,
⇒14 quarter pounds burger can be made.
Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef
Step-by-step explanation:
Answer:
38°
Step-by-step explanation:
Complementary means that they add up to 90
So then to find the measure of angle 2, subtract the measure of angle 1 from 90.
90-52=<u>38</u>
Formula for area of parallelogram:
A= bh
Where b is the length of base and h is the height.
Here b=2.3+4.5 = 6.8 cm
and h= 4.5 cm
Put values in formula.
A= 6.8 x 4.5
A=30.6 cm²
Answer: 30.6 cm²
I think it's D. The area of A is k2 times the area of rectangle B
