Using the formula (a-b)^2=a^2-2ab-b^2, you can plug in the values to get your answer. (Sorry I can't really explain more, it's just using the formula. Hope this helps)
Multiply the factors by FOIL technique and write the answer in Standard Form (y=ax^2+bx+c): y=(2x+3)(x-3) *
Answer:
2x^2 - 3x - 9
Step-by-step explanation:
y=(2x+3)(x-3)
Multiply using FOIL
2x × x
2x × -3
3 × x
3 × -3
2x^2 - 6x + 3x - 9
Combine like terms

Answer:
x = 85°Step-by-step explanation:
Sum of interior angles of any triangle is 180°:
52° + 43° + x = 180°95° + x = 180°x = 180° - 95°x = 85°One-fourth of a number is five-eights. Find the number. Simplify your answer
Answer:
2.50 or 2.5
Step-by-step explanation:
1/4=.25 so 25% of a number=5/8=0.625
So we multiply .625*4 to get the number. Since it's 25% and we want 100% to get it back to the original number
.625*4=2.50 or 2.5

(1 point)
(5x)
(3x+28)
O 14
O20
O 12
O 19
Answer:
x = 14
Step-by-step explanation:
The triangle has 2 congruent legs and is isosceles with 2 base angles being congruent , then
5x = 3x + 28 ( subtract 3x from both sides )
2x = 28 ( divide both sides by 2 )
x = 14

The inequality represent the given graph is y≤7 . Therefore, option B is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
From the given graph, the line passes through (0, -7)
In the given graph the inequality is y≤7
Therefore, option B is the correct answer.
