Answer:

91 in²

Step-by-step explanation:

We have to find the area of the individual shapes first, and then add them together. A square's area formula is bxh.

7x7=49.

A triangle's formula is BxH(1/2)

So 7x12=84

84/2=42

Now we add them together. 42+49=91.

I NEED HELP NOW ur really gonna need to solve this 10t-5=60

faltersainse [42]

Answer:

$\huge \: t = \frac{13}{2}$

Step-by-step explanation:

$10t - 5 = 60$

Using the addition property add 5 to both sides of the equation

That's

$10t - 5 + 5 = 60 + 5 \\ 10t = 65$

Divide both sides by 10

$\frac{10t}{10} = \frac{65}{10} \\ t = \frac{65}{10}$

Reduce the fraction with 5

We have the final answer as

$t = \frac{13}{2} \\$

Hope this helps you

What is the remainder when the polynomial f(x)=3x^3-4x^2+2x+8 is divided by (x-5)

yaroslaw [1]

The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).

Substitute x = 5 to the polynomial:

$f(5)=3(5^3)-4(5^2)+2(5)+8=3(125)-4(25)+10+8\\\\=375-100+18=275+18=293$

Answer: (3x³ - 4x² + 2x + 8) : (x - 5) = q(x) + 293.
