Can someone please tell me how to expand and simplify 4(x+1)^2?
[ i know now to expand brackets like (x+2)^2, but the 4 confuses me]
Expand the binomial first, then distribute the 4:
4 (x + 1)² = 4 (x ² + 2x + 1)
… = 4•x ² + 4•2x + 4•1
… = 4x ² + 8x + 4

Madeline is going to invest in an account paying an interest rate of 4.4% compounded
annually. How much would Madeline need to invest, to the nearest ten dollars, for
the value of the account to reach $16,600 in 12 years?
Answer:
$9540
Step-by-step explanation:

PLZZZ HELP MEE ILL GIVE BRAINLIEST AND 50 POINTS!!!
Answer:
The answer would be 45.
Step-by-step explanation:
5*9=45
Answer:
45
Step-by-step explanation:
First we count how many people he split it between which is 5 and we have to remember the key word here is equal so if he was left with 9 then everybody else did as well. so we multiply 5 times 9 which is 45
The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle.
Answer: 6
Step-by-step explanation:
Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:
Shorter leg² = 10² - 8²
Shorter leg² = 100 - 64
Shorter leg² = 36
Shorter leg = ✓36
Shorter leg = 6

Denise rode 3 kilometres .
Clark rode 5000 metres which is 5 kilometres .
So , Clark rode 2 kilometres more than Denise .
Answer:
Step-by-step explanation:

Rachel left home for school at 7:45 one morning. She returned home at 4:05 that afternoon. How many hours and minutes was she gone? (The number of minutes in your answer must be less than 60.)
Answer:
8 hours 20 minutes
Step-by-step explanation:
Given that :
Time Rachel left for school = 7:45 a.m
Time she returned Home = 4:05 p.m
Time for which Rachael was gone :
4:05 p.m - 7:45 a.m
7:45 a.m to 3:45 p.m= 8 hours
3:45pm to 4:05 pm = 20 minutes
= 8 hours 20 minutes
Rachael was gone for 8 hours 20 minutes
what is the value of X enter your answer in the box
Answer:
Step-by-step explanation:
Set up the following ratio which applies to all angle bisectors and the side opposite.
8 / (x + 4) = 12 / (2x + 1) Cross multiply
8 * (2x + 1) = 12 * (x + 4)
16x + 8 = 12x + 48 Subtract 8 from both sides
16x + 8 -8 = 12x + 48-8
16x = 12x + 40 Subtract 12x from both sides
16x - 12x = 40
4x = 40 Divide by 4
4x/4 = 40/4
x = 10
A line is parallel to y = 3x + 5 and
intersects the point (-2, 6). What is
the equation of this parallel line?
Start by entering this into point-slope form.
y- [?] = [](x
](x-[]).
Answer:
Im not like 100% sure but i think you answer is
y-6=3[x-(-2)]
y=6+3x+6
y=3x+12
And i believe that this is parallel to y
Answer:
y = 3x + 12Step-by-step explanation:
Parallel lines have same slope
Given line
y = 3x + 5The line that passes through (-2, 6) and with the slope of 3 is:
y - y₁ = m(x - x₁)y - 6 = 3(x - (-2))y - 6 = 3(x + 2)Convert the equation into slope-intercept form:
y - 6 = 3x + 6y = 3x + 6 + 6y = 3x + 12Is Janelle correct? Yes, because the lines are not parallel. Yes, because the lines will intersect. No, because the lines are in the same plane. No, because the lines are perpendicular.
Answer:
Step-by-step explanation:
No, because the lines are in the same plane.

15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)
Answer:
4,3cm
Step-by-step explanation:
Passo 1
Um losango tem 2 diagonais, cujos comprimentos não são iguais
Temos que encontrar o comprimento da segunda diagonal
A fórmula é dada como:
Área de um losango = 1/2 (d1 × d2)
Área do losango = 12 cm²
d1 = Comprimento da primeira diagonal = 8cm
d2 = Comprimento da segunda diagonal = x
12 = 1/2 (8 × x)
12 = 1/2 (8x)
12 = 4x
x = 12/4
x = 3cm
O comprimento da segunda diagonal = 3 cm
Passo 2
A fórmula do comprimento da lateral de um losango é dada como:
s = √d1² + d2² / 2
d1 = 8cm
d2 = 3 cm
s = √8² + 3² / 2
s = √64 + 9/2
s = √73 / 2
s = 8,5440037453 / 2
s = 4,2720018727 cm
Aproximadamente = 4,3 cm
