A triangle is B x H divided by 2. If the area is 30, then to work backwards we multiply it by 2. That gets us 60, and if one of the sides is 6, that can only mean it’s 10

Answer:

Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

John wants to make two frames for his artwork. One frame requires 3 1/2 feet of molding the other requires 4 2/3 feet of the sam
Damm [24]

no because if you make each fraction equal , the first would be 3 3/6 feet of molding and the other would be 4 4/6 feet and if you add those together you would get 8 1/6 which is less than 8 3/5

3. Diego drew a scaled version of a Polygon P and labeled it Q.
bogdanovich [222]

Answer:

The scale factor used to go from P to Q is 1/4

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x -----> area of polygon Q

y -----> area of polygon P

z^{2}=\frac{x}{y}

we have

y=72\ units^2

Find the area of polygon Q

Divide the the area of polygon Q in two triangles and three squares

The area of the polygon Q is equal to the area of two triangles plus the area of three squares

see the attached figure N 2

Find the area of triangle 1

A=(1/2)(1)(2)=1\ units^2

Find the area of three squares (A2,A3 and A4)

A=3(1)^2=3\ units^2

Find the area of triangle 5

A=(1/2)(1)(1)=0.5\ units^2

The area of polygon Q is

x=1+3+0.5=4.5\ units^2

Find the scale factor

z^{2}=\frac{x}{y}

we havey=72\ units^2

x=4.5\ units^2

substitute and solve for z

z^{2}=\frac{4.5}{72}

z^{2}=\frac{1}{16}

square root both sides

z=\frac{1}{4}

therefore

The scale factor used to go from P to Q is 1/4

one x-intercept for a parabola is at the point (1,0). Use the factor method to find the other x-intercept for the parabola defin
viktelen [127]

Answer:

4x^2 + 4x - 8 = 4*(x^2 + x - 2)

(x - 1) * (x - a) = x^2 + x - 2 --> a = -2
